The Two Legs Hammer Curl with Towel (Version 2) is a bodyweight strength exercise that primarily targets the brachioradialis, with the biceps brachii and brachialis as synergists. You loop a towel under both feet simultaneously and curl with a neutral (palms-facing-each-other) grip, using leg pressure to generate resistance. It is an effective option for building forearm and upper-arm strength at home or while traveling with no equipment beyond a towel.
Cómo hacer el Two Legs Hammer Curl with Towel (VERSION 2)
- 1Sit on the floor with your legs extended in front of you. Loop the center of a towel under the arches of both feet so an end hangs on each side.
- 2Hold one end of the towel in each hand with a neutral grip — palms facing each other — and let your arms extend fully toward your feet.
- 3Sit tall with your spine upright, shoulders pulled back and down, and your core lightly braced.
- 4Press both feet firmly into the towel to create tension, then begin curling your fists toward your shoulders in a smooth arc.
- 5Keep your elbows close to your sides and stationary throughout — only your forearms should move.
- 6Curl until your fists reach shoulder height and you feel a strong contraction across your forearms and upper arms.
- 7Lower your hands slowly back toward your feet, resisting the pull of your legs through the towel for a controlled eccentric.
- 8Complete all reps, then release foot pressure and set the towel down.
Consejos de técnica
- Dial resistance up or down by adjusting knee bend — straightening your legs increases towel tension, bending them reduces it.
- Take at least two counts on the lowering phase; the eccentric portion builds brachioradialis strength as much as the curl itself.
- Lock your wrists in a neutral position throughout and do not let them flex or extend as you curl — a wobbling wrist bleeds tension from the forearm.
- Squeeze the towel firmly throughout each rep to maximize forearm recruitment and brachioradialis engagement.
Errores comunes
- Rocking the torso backward at the top of the curl, which turns the movement into a partial body-row and removes tension from the elbow flexors.
- Letting the elbows drift forward or upward, which recruits the front deltoids and reduces the load placed on the brachioradialis and brachialis.
- Applying too little foot pressure on the towel, leaving it slack and eliminating meaningful resistance through the range of motion.
- Rushing through the lowering phase, which discards the eccentric load responsible for a large share of muscle stimulus and strength adaptation.
- Gripping the towel with a supinated (underhand) wrist, which shifts emphasis to the biceps brachii and defeats the purpose of the neutral-grip hammer variation.
Preguntas frecuentes
What muscles does the Two Legs Hammer Curl with Towel (Version 2) work?
The primary target is the brachioradialis — the large muscle running along the outer forearm — with the biceps brachii and brachialis contributing as synergists for elbow flexion.
How is Version 2 different from Version 1 of this exercise?
Version 2 uses both legs simultaneously to apply tension through the towel, providing more stable and evenly distributed resistance across the movement. Version 1 typically uses only a single leg, which creates a slightly different resistance curve and requires more balance.
How do I make this exercise harder without adding equipment?
Straighten your legs further to increase towel tension, slow the lowering phase to 3–4 counts, or pause for 1–2 seconds at the top of each rep to extend time under tension.
Is the Two Legs Hammer Curl with Towel good for beginners?
Yes. Because resistance is controlled entirely by how much pressure you apply with your feet, beginners can start at a comfortable tension level and progressively increase it as strength improves.
How many sets and reps should I do?
Aim for 3 sets of 12–15 reps. Since load is limited by bodyweight, higher rep ranges tend to work well for building forearm and upper-arm endurance and hypertrophy.
