Lying Double Legs Hammer Curl With Towel

Body Part: Upper Arms

Muscle: Biceps

Equipment: Body Weight

Lying Double Legs Hammer Curl With Towel is a floor-based biceps drill that uses a towel and both legs as the resistance anchor. The neutral or hammer grip shifts the emphasis toward the biceps, brachialis, and brachioradialis while the supine position makes it easier to keep the shoulders quiet and the torso from swinging. It is a useful option when you want arm work without standing momentum or heavy external loading.

The setup matters because the towel tension, foot position, and elbow path determine whether the rep stays on the arms or gets turned into a tug-of-war with the hips and shoulders. Lie on your back, raise both legs, and loop or brace the towel so the feet can hold a steady anchor. Keep the wrists stacked and the elbows close to your sides before you start curling.

Each rep should look like a strict hammer curl performed on the floor. Pull the towel ends toward your shoulders by bending the elbows, then lower under control until the arms are nearly straight again. The legs stay lifted and firm so the towel remains taut, but the upper arms should not drift forward. Breathing should stay calm and rhythmic, with the exhale on the curl.

This movement is best used as accessory arm work, a controlled finisher, or a lighter technique exercise when you want to train elbow flexion with minimal equipment. It is not meant to be explosive. Clean reps, a neutral wrist, and a steady lowering phase matter more than the number of repetitions. If the shoulders tense up or the low back arches, reduce the tension and shorten the set.

Because the towel anchor and floor position limit cheating, this exercise can be a good choice for beginners, home workouts, or travel sessions. It also works well when you want to feel the forearm and upper-arm stabilizers working together without needing dumbbells or a machine. Keep the motion smooth, keep the legs steady, and stop the set before the towel position or elbow angle starts to break down.

Instructions

• Lie on your back on a mat and raise both legs so the knees are bent and the feet can hold the towel in front of you.
• Loop or brace the towel across both feet and take the ends in a neutral hammer grip, with palms facing each other.
• Set your shoulder blades down, keep your lower back gently pressed into the floor, and pinch the towel so it stays taut.
• Start with the elbows close to your ribs and the arms nearly straight without locking them out hard.
• Curl the towel ends toward your shoulders by bending only at the elbows, keeping the wrists straight and the upper arms still.
• Hold the top position briefly when the hands are close to the chest and the biceps are fully shortened.
• Lower the towel back down in a slow, controlled arc until the elbows are nearly straight again.
• Keep the feet and legs steady throughout the rep so the towel stays under tension instead of slackening.
• Exhale as you curl up, inhale on the way down, and reset your shoulder position before the next repetition.

Tips & Tricks

• Keep the grip neutral the whole time; turning the wrists into a supinated curl changes the feel of the exercise.
• If your shoulders start to lift off the floor, the towel is probably too tight or your elbows are drifting forward.
• Think about dragging the towel ends toward the front of your shoulders, not swinging them toward your face.
• A small bend in the knees helps keep the towel anchored and reduces strain on the low back.
• Do not let the elbows flare wide; the closer they stay to your ribs, the cleaner the hammer-curl line stays.
• Use a slower lowering phase than the lifting phase to keep tension on the biceps and forearms.
• Keep the feet firm but not cramping; the towel should feel secure, not like you are fighting a full-body isometric hold.
• Stop the set if your wrists collapse backward or the towel starts sliding instead of staying taut.

Frequently Asked Questions

What does the towel do in this hammer curl?

The towel gives you a light, controllable resistance anchor so you can train the curl pattern without dumbbells or a machine.

Why are both legs raised during the exercise?

The elevated legs help hold the towel taut and keep the setup stable while you curl from the floor.

What muscles does this exercise work most?

The main work goes to the biceps, with strong help from the brachialis and brachioradialis.

Should my elbows move forward when I curl the towel?

No. Keep the elbows tucked near your ribs so the rep stays on the arms instead of turning into a shoulder movement.

How hard should I squeeze the towel?

Squeeze it firmly enough to keep tension, but not so hard that your forearms cramp before the biceps are tired.

Is this exercise good for beginners?

Yes. The floor position and neutral grip make it easy to keep the motion strict and reduce cheating.

What is the most common mistake?

Letting the towel go slack or letting the shoulders roll forward, which steals tension from the arms.

How do I know if the load is right?

The rep should feel smooth and controlled from bottom to top, with no jerking, wrist collapse, or low-back arching.
