Two Legs Hammer Curl with Towel

Beginner to Intermediate Towel + Bodyweight Resistance Biceps / Brachialis / Forearms
The Two Legs Hammer Curl with Towel is a clever self-resistance arm exercise that uses a towel looped under both feet to create tension while you perform a neutral-grip curl. This movement primarily targets the biceps, brachialis, and forearms, while the core works hard to stabilize the body in the seated position. The key is to keep the motion controlled, maintain steady towel tension, and curl with the elbows rather than jerking with the torso.

This exercise is a great option for home training when you want to challenge the arms without dumbbells. Because the resistance comes from your own legs pushing against the curl, you can instantly adjust intensity rep by rep. The neutral hammer grip shifts extra emphasis onto the brachialis and brachioradialis, making it useful for building arm thickness and grip-related strength.

Safety tip: Keep your spine long, avoid yanking the towel, and do not let your lower back collapse. Use smooth resistance from both legs instead of sudden jerking. If you feel wrist pain, elbow discomfort, or lower-back strain, reduce tension and tighten your setup.

Difficulty Beginner to Intermediate

Sets & Reps (By Goal)

  • Muscle building: 3–4 sets × 8–15 reps with controlled self-resistance and 45–75 seconds rest
  • Arm endurance: 2–4 sets × 15–20 reps using moderate tension and a steady tempo
  • Home strength practice: 3–5 sets × 6–10 reps with stronger leg resistance and slower eccentrics
  • Finisher work: 1–2 sets close to technical fatigue after your main arm session

Progression rule: First improve control, range, and squeeze quality. Then increase resistance by pressing harder through the legs or slowing the lowering phase.

Setup / Starting Position

  1. Sit on the floor: Lean back slightly with your chest up and core engaged.
  2. Raise both legs: Keep the feet elevated and loop a towel securely under both feet.
  3. Grab the towel ends: Hold one end in each hand with a neutral hammer grip, palms facing each other.
  4. Set arm position: Start with the elbows partially extended in front of the body, not locked out stiffly.
  5. Create tension: Push lightly through the legs and pull with the arms so the towel already feels loaded before the first rep.

Tip: Sit tall and keep the shoulders down. Your goal is to make the curl hard with tension, not by swinging the body.

Execution (Step-by-Step)

  1. Brace your position: Tighten the core, keep the torso steady, and hold the feet up with the towel anchored under them.
  2. Start curling: Bend the elbows and pull the towel handles toward your torso while the legs resist the motion.
  3. Keep the grip neutral: Maintain a hammer-curl hand position throughout the rep to emphasize the brachialis and forearms.
  4. Reach peak contraction: Bring the hands in toward the chest without shrugging the shoulders or collapsing posture.
  5. Lower slowly: Extend the arms under control while continuing to resist with the legs so the towel stays tight on the way down.
  6. Repeat smoothly: Perform each rep with constant tension and no bouncing or jerking.
Form checkpoint: If your elbows flare too much, your legs drop quickly, or your torso rocks back and forth, you are using momentum instead of controlled self-resistance. Reduce tension and clean up the movement.

Pro Tips & Common Mistakes

  • Keep towel tension constant: Do not let the towel go slack between reps.
  • Use the legs intelligently: The feet should resist the curl, not overpower it so much that range disappears.
  • Stay in a strong seated position: Avoid rounding the back or collapsing the chest.
  • Keep the elbows driving the curl: Do not turn it into a rowing motion.
  • Control the lowering phase: The eccentric portion adds a lot of training value in self-resistance exercises.
  • Do not rush: A slower tempo improves both muscular tension and technique quality.
  • Watch wrist position: Keep the wrists neutral instead of bending them sharply inward or backward.

FAQ

What muscles does the Two Legs Hammer Curl with Towel work?

It mainly trains the biceps, brachialis, and brachioradialis. Because you hold the position seated with the legs elevated, the core and hip flexors also help stabilize the body.

Why use a hammer grip instead of a regular underhand curl?

The neutral hammer grip increases emphasis on the brachialis and forearms, which can help improve total arm thickness and support stronger curling performance overall.

Is this a good exercise if I do not have weights at home?

Yes. This is one of the better no-weight arm exercises because you can create meaningful resistance by using your legs against the pulling action of the arms.

How hard should I push with my legs?

Use enough leg resistance to make the curl challenging while still allowing a full, controlled range of motion. Too much resistance turns the rep into a short isometric grind, while too little makes it too easy.

Can beginners do this exercise?

Yes. Beginners can start with lighter resistance and a smaller lean-back angle. As control improves, they can increase towel tension, rep quality, and total volume.
