How to Exercise Your Fingers, 3 Methods…

How to Exercise Your Fingers

Three Methods:
1- Warming Up Your Fingers
2- Performing Finger-Strengthening Exercises
3- Exercising Fingers and Grip for More Strenuous Activities

Do you have weak fingers? Do you need to use them for something that requires flexibility? Do you want to have a better grip on jars and lids and slippery objects? How about holds for rock climbing or weightlifting? The right exercises can help improve the flexibility, suppleness, and strength of the joints to help people perform everything from basic activities of daily living to higher level physical activities.


Warming Up Your Fingers

  1. Image titled 117181 1

    Warm up your fingers. Warming up is important part of any exercise routine. This includes your fingers.
  2. Massage the top and palm of your hand. Using the thumb, move in slow, circular strokes with medium-deep pressure for the massage. Do not put pressure to the point of pain.

    • Massage for one to two minutes to help loosen and warm the muscles in the hands. This will get you the most out of your exercise routine.
  3. Bend each finger. Bend each finger back until you feel a slight stretching. Then bend each finger forward. Do not perform to the point of pain.
  4. Soak hands in warm water. Soaking your hands for ten minutes or so before beginning exercises can warm them up and increase flexibility.

    • Treating your hands with a warm paraffin wax bath can also be very helpful.


Performing Finger-Strengthening Exercises

  1. Hold your fist closed. Make a fist. Keep your thumb across your fingers and not tucked. Hold this pose for thirty seconds to a minute. Release it and spread the fingers out widely.[1] Begin with four reps of this if possible.

    • If you cannot do four reps of any of these exercises at first, don’t worry. Do what you can without straining your muscles. You will find that you naturally build up to more reps with time.
    • Be sure to consult with a physician or physical therapist before adding more than the recommended amount of reps to avoid the possibility of straining your hands.
  2. Flatten each hand against a flat surface. Place your hand palm-down on a table. Flatten the hand against the table’s surface as much as possible. Hold that pose for thirty second to a minute,[2] then release. Begin with four reps of this if possible.
  3. Squeeze a soft ball. For a grip-strengthening exercise, hold a soft ball in your palm and squeeze it hard for five seconds before releasing your grip. Work your way up to 10–15 repetitions, performed two to three times weekly. It is important to give yourself two days’ rest between grip-strengthening sessions.

    • Do not perform this exercise if you have a thumb injury.
  4. Do “claw stretches. In this exercise, called the “claw stretch,” hold your hands out in front of you, so you can visualize your palms. Then bend your fingers so that the tips rest against the base of your finger joints. Your hand will resemble a cat’s paw. Hold for thirty seconds to a minute before releasing.[3] Do four reps if possible.
  5. Touch your thumb to each of your fingers. One at a time, touch the pad of your thumb to the tip of each finger. Make sure that each touch makes an “O” shape. Do four reps of this exercise if possible.

    • You can also do this exercise by touching your thumb to the pad of each finger. The shape made by your fingers will be more of an oval or egg shape.
  6. Do pinch strengtheners. To perform this exercise, pinch a bit of silly putty or a soft ball between the tips of your fingers and your thumb. Hold the pinch for thirty seconds to a minute. Build up to 10–15 repetitions if possible. You can perform two to three times each week with a two-day rest period between sessions.[4]

    • Do not perform if you have a thumb injury.[5]
  7. Perform finger lifts. Place your hands flat on a table with your palms down. Lift up one finger at a time, then lower it. At the end, lift up all four fingers and the thumb then lower them. Do four reps of this if possible.
  8. Incorporate a rubber band. Wrap a rubber band around your hand at the base of the fingers. Extend the thumb and hold it before bringing it back in. If possible, work up to 10–15 reps. It is safe to do these exercises two to three times a week, but give your hands two days to rest between sets.[6]
  9. Do thumb-to-pinkie touches. Hold out your hand in front of you. Extend the thumb away from the hand as far as comfortable. Bend the thumb across the bottom of your hand to touch the base of your pinkie finger. Hold each pose for thirty seconds to a minute. Work up to four reps to begin with.
  10. Do finger abduction and adduction exercises. This involves squeezing the fingers together and pulling the fingers apart from each other. Interlock your fingers and try to pull one hand away while the fingers of the other hand are squeezing towards each other trying to maintain the interlock.

    • For strengthening the thumb to the pad of your fingers, you can put a piece of paper between thumb and pad, squeeze, and with opposite hand try to pull the paper from between your thumb and finger.


Exercising Fingers and Grip for More Strenuous Activities

  1. Image titled Exercise Your Fingers Step 15

    Utilize both isometric and dynamic strength-training activities. Climbers, bodybuilders, and others who use their hands and fingers for strenuous physical activity may also want to exercise fingers to increase strength. Two key components for exercising fingers include a balance of isometric and dynamic training activities.

    • An isometric activity means holding a static position for an extended period of time.  A rock climber hanging by a particular grip while choosing his or her next move is an example of an isometric activity.
    • A dynamic activity means moving a part of the body while supporting a load with the same part. A push-up is a great example. You can see how you’re moving your arms during a push-up while supporting the load of your body on them as well.
    • Going from a dead hang (isometric) into a pull-up (dynamic) is an example of an exercise that offers both. You can even tailor pull-ups to include exercising your fingers by keeping your grip on the bar closer to your fingertips than the palms of your hands.
    • Make sure the when you are doing exercises where the hand/palm is holding the body up (push ups, planks, etc.), you are pressing through your knuckles and fingertips and not sinking into your wrists; this can cause wrist injury.
  2. Image titled Exercise Your Fingers Step 16

    Focus on tendons. Tendons are the sinew that connect muscles to bones and transmit force between them. Finger strength has more to do with the strength of the tendons that connect your finger bones to your forearm muscles than anything else.Tendons take longer to strengthen and less time to degenerate, so you must stick to a disciplined workout regimen.

  3. Exercise with a high focus on grip. One of the easiest ways to exercise fingers is to keep the emphasis on your grip rather than simply the forearm and bicep muscles. When you transition too much of the load onto your arm muscles, then your fingers don’t get as intense of a work out, even when your hands are involved in holding the weight.
  4. Use a hammer grip when lifting weights. A hammer grip is when you keep your palms facing one another during the range of motion while lifting a weight.Used most commonly with dumbbells, a hammer grip keeps the load on your fingers instead of resting it on the palms of your hands. This forces you to squeeze hard to keep your grip over several reps, which works both the finger tendons and associated forearm muscles.
  5. Image titled Exercise Your Fingers Step 19

    Increase the girth of your grip. Another way to keep the attention of your finger tendons and forearm muscles is to use a wider grip.A wider grip means you will have to squeeze harder to maintain your grip. You can purchase a specialty strength-training item such as Fat Gripz to go over a pull-up, dumbbell, or barbell to add more circumference, or you can simply wrap a household item such as a towel around the bar.
  6. Use handgrips. They may not be as glamorous as lifting large weights, but a plain old pair of handgrips with the metal tension coil between them can help you exercise your fingers as well. If you cannot find a pair, you can also squeeze a tennis ball, racquetball, or another household item with some give to it.
  7. Image titled Exercise Your Fingers Step 21

    Train progressively. Do not start by training to do chin-ups with only a few fingers on each hand or anything else beyond your training level. Tendon injuries require long periods of rehabilitation and often never return to pre-injury levels. The best thing you can do is train progressively.Finger strength will develop slowly, so start easy and develop a more difficult routine over several months rather than weeks.

Cutting back on punishment helps kids with ADHD, study finds

Biological, behavioral improvements follow parenting classes

Cutting back on yelling, criticism and other harsh parenting approaches, including physical punishment, has the power to calm children with attention deficit hyperactivity disorder, according to a new study.

Researchers from The Ohio State University evaluated physiological markers of emotional regulation in preschool children with ADHD before and after a parent and child intervention aimed at improving family relations. Changes in parenting — including less yelling and physical discipline — led to improvements in children’s biological regulation.

“This is the first study to show that improved parenting changes kids biologically,” said Theodore Beauchaine, the study’s senior author and a professor of psychology at Ohio State.

“The idea is to change family dynamics so these highly vulnerable kids don’t run into big problems down the road, including delinquency and criminal behavior.”

The study appears in the journal Clinical Psychological Science.

Parents of 99 preschoolers with ADHD received parenting coaching — half during 20 weekly two-hour sessions and half during 10 similar sessions. The parents learned skills including problem-solving, positive parenting techniques and effective responses to their children’s behaviors. Meanwhile, their children met with therapists who reinforced topics such as emotional regulation and anger management.

Before the training began, parents (usually moms) and their children engaged in play sessions that included an intentionally frustrating block-building exercise. Parents dumped a large container of blocks on the floor and were told not to touch the blocks and to coach their children on how to build progressively complex structures.

During the exercise, the children were tethered to equipment that recorded their heart activity. Abnormal patterns of heart activity are common among children who have trouble controlling their emotions, including some children with ADHD, Beauchaine said.

After parent coaching was complete, the researchers had families return to the lab for retesting to determine if the training sessions led to changes in parenting and heart activity among children.

Reductions in negative parenting were found to drive improved biological function in children. Increases in positive parenting had no effect.

The researchers also observed each parent and child during a 30-minute play session in the family home and video-recorded positive and negative parenting approaches. Positive parenting included praise, encouragement and problem-solving. Negative parenting included critical statements, physical discipline and commands that gave children no opportunity to comply.

Less-harsh parenting also was linked to improved behavior in children, a finding that bolsters previous research in this area.

“Negative interactions between parents and children have a big effect on kids,” Beauchaine said.

Greater improvements in parenting were seen in those who had 20 weeks of classes, versus 10. Regardless, the intervention was relatively short, Beauchaine said.

“Just 20 weeks to observe this much change is somewhat surprising,” he said.

Children in the study all struggled primarily with hyperactivity and impulsivity, as opposed to inattention. Most of them — 76 percent — were boys, which is similar to ADHD rates in the general population. Families were participants in Beauchaine’s work with collaborators at the University of Washington. One limitation of the study is that it did not include a control group of parents and children who did not receive lessons.

Beauchaine said it is important to recognize the tremendous parenting challenges that moms and dads of children with ADHD face.

“A lot of times, these young kids and their parents don’t like each other much. We strive to change that. It’s challenging for parents, because these kids can be hard to raise,” he said.

“The idea is not to blame parents or kids, but to look for ways to help them both.”

Un guide suggère des activités pour des élèves ayant un TDAH


Des finissants en kinésiologie de l’Université de Sherbrooke ont créé un guide à l’intention des élèves de 5 à 12 ans ayant un trouble du déficit de l’attention avec ou sans hyperactivité (TDAH).

Avec Explose dans ta pause!, ils suggèrent des activités aux enseignants qui travaillent à leur côté.

Le guide regroupe 46 activités et compte quatre sections, qui se penchent sur les activités motrices, cognitives, sociales et individuelles. L’enseignant peut donc choisir l’activité à faire en fonction des besoins particuliers de sa classe. Le livre est accompagné d’une affiche à épingler dans la classe et des pictogrammes plastifiés représentant les différentes activités proposées.

Le projet a été réalisé dans le cadre d’un cours intitulé « Intervention auprès d’une population ».


Un autre groupe d’étudiants avait déjà évalué des besoins au sein de la population; ce portrait a servi de modèle de base pour cette initiative.

« Ils ont évalué le besoin dans les écoles de l’Estrie au niveau des jeunes qui ont un TDAH. On s’est basé là-dessus pour développer notre guide », remet en contexte la cheffe de projet, Emmanuelle de Vette. L’objectif qui en était ressorti était d’augmenter l’activité physique auprès des jeunes de 5 à 12 ans atteints de TDAH et du coup, améliorer leurs capacités cognitives et leur concentration.

« Au départ, on a fait une recherche dans la littérature à savoir ce qui est pertinent pour les enfants de 5 à 12 ans afin d’améliorer leur capacité de concentration. On a des enseignants qui nous ont aidés par rapport à certaines activités qu’on pouvait développer. Par la suite, on est intervenu auprès d’un milieu pour voir quels étaient les besoins », commente Jessika Gardner, directrice des communications et du marketing.

Les bienfaits ressortent dans la littérature. « L’activité physique secrète plusieurs hormones comme l’endorphine. Ça calme après. On l’a vécu : notre prof qui fait la revue technique nous a dit exactement ça. Les élèves sont plus calmes après l’activité », indique Emmanuelle.

« C’est important pour nous que ce soit applicable sur le terrain. »

Les activités pourraient aussi s’appliquer aux autres élèves, qui peuvent bénéficier des bienfaits de l’activité physique.

Les étudiants ont aussi réalisé des vidéos d’activités, comme du yoga et du zumba, sur une chaîne YouTube.

Le lancement du guide aura lieu ce jeudi à 18 h au Carrefour de l’information de l’UdeS. Au total, 17 étudiants ont participé.
