Two Legs Hammer Curl With Towel Version 2

Body Part: Upper Arms

Muscle: Other

Equipment: Body Weight

Two Legs Hammer Curl With Towel Version 2 is a seated towel-resistance curl performed on the floor with both feet looped into the towel and the hands holding the ends in a neutral hammer grip. The setup shown in the image makes this a control-first arm drill: your torso stays slightly reclined, your elbows stay close to your sides, and the towel creates the resistance line between your hands and both feet.

The main training value is not just elbow flexion, but the ability to keep the upper arms, forearms, grip, and trunk organized while the towel stays taut. Because both legs are involved, the movement asks for more coordination than a normal curl. If the feet drift, the towel twists, or the torso rocks back and forth, the work shifts away from the intended arm pattern and into momentum.

A good rep starts with the towel centered across both feet or arches, the palms facing in, and the shoulders stacked down away from the ears. From that position, curl the hands toward the lower ribs while keeping the wrists straight and the elbows pinned close enough that the pull stays clean. The legs should remain together and controlled rather than flaring apart, and the reclined torso should stay steady instead of swinging through the effort.

This exercise is useful as light strength work, a warm-up for the elbows and forearms, or an accessory movement when you want a low-load bodyweight challenge that still demands precision. It also works well when you want to train grip endurance without heavy external loading. Because the towel can shift easily, the quality of the setup matters more than the number of reps.

Use smooth breathing, a slow return, and a short range only as wide as you can keep under tension. If the towel starts slipping, the shoulders rise, or the lower back begins to take over, reduce the effort and clean up the position. The best version of this movement looks quiet and deliberate from start to finish, with the hands, elbows, and feet staying connected to the same line of tension.

Instructions

• Sit on the floor with both legs extended forward and a towel looped under both feet or arches.
• Hold one towel end in each hand with your palms facing in and your elbows resting close to your ribs.
• Lean back slightly with your chest lifted, shoulders down, and both feet secured evenly in the towel.
• Set your wrists straight and brace your midsection before you start the curl.
• Pull the towel ends toward your lower ribs by bending your elbows, not by rocking your torso.
• Keep the knees and feet together as the towel stays taut and the hands travel back.
• Pause briefly when the hands are closest to the body and the elbows are fully flexed.
• Lower under control until the arms re-extend and the towel tension stays even.
• Reset your posture before the next rep and repeat for the planned set.

Tips & Tricks

• Keep the towel centered across both arches so one foot does not slide ahead of the other.
• Use a neutral hammer grip the whole time; turning the palms in or out changes the load on the forearms.
• If your shoulders start creeping up, sit a little taller and shorten the pull.
• Do not let the lower back become the driver; the torso should stay mostly fixed while the elbows move.
• A slower return usually works better here than a hard pull, because the towel can jerk out of position.
• Keep your wrists stacked over your forearms instead of letting them bend back when the towel gets tight.
• Exhale as the hands curl in and inhale as you lengthen back out.
• If the towel feels slick, use a thicker or grippier towel before adding more effort.

Frequently Asked Questions

What muscles does Two Legs Hammer Curl With Towel Version 2 work?

It emphasizes the biceps, forearms, and grip, while the shoulders and trunk help keep the seated position stable.

Where should the towel sit on my feet?

Loop it across both arches or the front of the feet so the towel stays even and the pull line is centered.

Should my palms stay facing each other the whole time?

Yes. Keeping a neutral hammer grip is part of the exercise and keeps the load focused on the arm flexors and forearms.

Do my knees actually move during the rep?

They can bend slightly as you pull, but the movement should stay smooth and controlled rather than turning into a full-body swing.

Is this a good beginner exercise?

Yes, if you keep the tension light and focus on a slow, clean pull with no torso rocking.

What is the most common mistake with this movement?

Letting the shoulders shrug and the back swing to finish the curl instead of keeping the elbows and ribs organized.

Can I use a resistance band instead of a towel?

You can, but a band changes the feel of the pull; use the towel version if you want the exact seated foot-loop setup shown here.

What should I do if the towel slips in my hands?

Shorten the towel, choose a grippier one, or reduce the effort until you can keep the line of tension stable.
