Finger Extensor Bands
Almost every armwrestling exercise trains the closing/flexing side of the hand — finger extensor bands are the cheap, two-minute fix for the opening-side imbalance that follows.
What It Is
Finger extensor bands are small elastic loops worn around the fingertips that you open against, training the finger and hand extensor muscles most gripping and pulling exercises never touch. Armwrestling training is almost entirely closing/flexing-dominant (cupping, gripping, pulling), so the opening muscles are chronically undertrained unless you deliberately add them back in.
Who It's For
Every armwrestler, honestly — this is one of the cheapest, highest-value injury-prevention tools in the sport, especially for anyone doing heavy grip or cupping work without any counterbalancing extensor training.
How to Choose
- •Buy a set with a range of resistance levels rather than a single-tension band — you’ll want lighter resistance for rehab-style work and higher for pure strength
- •Latex bands wear out faster with heavy grip-sweat exposure than silicone alternatives; either works, but replace them once they lose tension
How to Use It
- 1Place the band around all five fingertips and open your hand fully against the resistance, then return under control
- 2Do this as a warm-up before heavy gripping or cupping work, and again as a cooldown afterward, to balance the flexor-dominant volume of the rest of your session
- 3Two to three sets of 15-20 controlled openings is enough — this is a prehab tool, not a max-strength exercise
Pro Tips
- •If you’ve ever felt tightness or early tendinitis symptoms on the back of your hand or forearm after heavy grip training, this is usually the first fix a coach will suggest
- •Keep a set in your gym bag — it takes under two minutes and has an outsized effect on long-term wrist and finger health for how little time it costs
Buying Mistakes to Avoid
- ✕Buying a single-tension band set instead of a graduated range, limiting use to only one training purpose
- ✕Skipping this entirely because it feels too light to matter, then dealing with early tendinitis symptoms from an untrained extensor imbalance

Do I really need finger extensor training as an armwrestler?
Yes — armwrestling training is almost entirely closing-dominant (cupping, gripping, pulling), so the finger and hand extensor muscles are chronically undertrained unless you deliberately add them back with a cheap band.
