The Two Legs Reverse Biceps Curl with Towel (Version 2) is a bodyweight strength exercise that primarily targets the biceps brachii, with the brachialis and brachioradialis assisting throughout the movement. You loop a towel under both feet, grip each end with an overhand (pronated) grip, and curl upward against the resistance of your own bodyweight. It is a practical option for building upper-arm and forearm strength anywhere you have a towel and enough floor space.

Cómo hacer el Two Legs Reverse Biceps Curl with Towel (VERSION 2)

  1. 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 one end hangs on each side.
  2. 2Grip each end of the towel with an overhand grip — palms facing down toward the floor — and let your arms extend fully toward your feet.
  3. 3Sit tall with your spine upright, shoulders pulled back and down, and your core lightly braced.
  4. 4Press both feet firmly into the towel to create tension before you begin the curl.
  5. 5Initiate the movement by curling your fists toward your shoulders in a smooth arc, keeping your palms facing downward throughout.
  6. 6Hold your elbows close to your sides and stationary — only your forearms should move.
  7. 7Curl until your fists approach shoulder height and you feel a strong contraction in your upper arms and forearms.
  8. 8Lower your hands slowly back toward your feet, resisting the pull of your legs through the towel for a controlled eccentric.
  9. 9Complete all reps, then release foot pressure and set the towel down.

Consejos de técnica

  • Maintain the pronated (overhand) grip from start to finish — rotating your wrists at any point shifts emphasis away from the target muscles and reduces the effectiveness of the reverse curl.
  • Adjust resistance by changing your leg position: straightening your legs increases towel tension, bending your knees reduces it.
  • Take at least two full counts on the lowering phase; a slow eccentric builds as much strength in the brachialis and brachioradialis as the curl itself.
  • Keep your wrists flat and neutral throughout — do not let them extend or flex under load, as wrist wobble bleeds tension from the forearms and strains the joint.
  • Squeeze the towel firmly on each rep to maximize engagement across the forearm musculature.

Errores comunes

  • Rotating the grip to a supinated (underhand) position at the top of the curl, which transfers emphasis to the biceps brachii long head and defeats the purpose of the reverse-curl variation.
  • Rocking the torso backward as the arms approach the top, which turns the movement into a partial body-row and removes the load from the elbow flexors.
  • Letting the elbows drift forward or upward during the curl, which recruits the front deltoids and reduces isolation of the brachialis and brachioradialis.
  • Applying insufficient foot pressure, leaving the towel slack and eliminating meaningful resistance through the range of motion.
  • Rushing through the lowering phase and losing the eccentric stimulus, which accounts for a large portion of the strength and hypertrophy adaptation.

Preguntas frecuentes

What muscles does the Two Legs Reverse Biceps Curl with Towel (Version 2) work?

It primarily targets the biceps brachii, with the brachialis and brachioradialis acting as synergists. The overhand grip places particular demand on the brachialis and brachioradialis compared to a standard supinated curl.

How is Version 2 different from Version 1 of this exercise?

Version 2 uses both legs simultaneously to apply tension through the towel, giving more stable and evenly distributed resistance across the movement. Version 1 typically uses a single leg, which creates a slightly different resistance curve and demands more balance.

Why use a reverse (overhand) grip instead of a regular curl grip?

A pronated grip reduces the mechanical advantage of the biceps brachii and shifts more of the load onto the brachialis and brachioradialis. This builds more balanced elbow-flexor strength and is particularly effective for forearm development.

How do I make this exercise harder without any equipment?

Straighten your legs further to increase towel tension, slow the lowering phase to 3–4 counts, or add a 1–2 second pause at the top of each rep to extend time under tension.

How many sets and reps should I do?

Aim for 3 sets of 12–15 reps. Because load is limited by bodyweight and towel tension, slightly higher rep ranges work well for building upper-arm and forearm endurance and hypertrophy.
