Lying Double Legs Biceps Curl With Towel

Body Part: Upper Arms

Muscle: Biceps

Equipment: Body Weight

Lying Double Legs Biceps Curl With Towel is a floor-based, self-resisted arm exercise that uses a towel and both legs to create tension without external weights. It is mainly a biceps movement, but it also asks the forearms, brachialis, and shoulder stabilizers to stay organized while you keep the towel tight and the body still. The lying position removes most of the standing sway that can hide sloppy curling, so the quality of the rep depends heavily on how well you set up before the first pull.

This variation is useful when you want a simple home option for direct arm work or a light accessory drill that still demands control. Because the legs are elevated and bent, the towel has to stay anchored while the arms do the curling work, which makes wrist position, elbow tracking, and shoulder tension more important than load. If the towel slips or the knees drift, the set turns into a grip-and-position fight instead of a clean biceps curl.

The best repetitions start with the towel secured around both feet or under both arches, hands holding the ends with the palms facing up and the elbows tucked close to the ribs. From there, curl the hands toward the shoulders while keeping the upper arms quiet and the ribcage down. A small pause at the top helps you feel the biceps shorten fully, and a slow lowering phase keeps the towel under tension so the set does not turn into a quick tug-and-release.

Because this is a self-resisted movement, the amount of effort comes from how tightly you pull against the towel and how steady you keep the lower body. That makes it a good choice for higher-rep arm work, warm-ups, or accessory work after heavier training. It is also easy to regress by shortening the lever and using less pull through the feet, or to make harder by increasing the tension and slowing the lowering phase.

Keep the motion clean and repeatable rather than chasing speed. If the shoulders shrug, the wrists bend back, or the knees drift toward the chest, reduce the pull and reset the position so the biceps stay in charge. The goal is a controlled curl with both legs fixed, both hands pulling evenly, and no wasted motion through the torso.

Instructions

• Lie on your back and bend both knees so your feet are lifted off the floor.
• Loop the towel around both feet or under the arches, then hold one end of the towel in each hand.
• Turn your palms up, tuck your elbows close to your ribs, and keep your shoulders heavy on the floor.
• Set the towel under tension before you start the first curl so the line stays tight from hands to feet.
• Curl both hands toward your shoulders while keeping the upper arms still and the knees in the same bent position.
• Squeeze the biceps at the top without letting the elbows flare or the wrists bend back.
• Lower the hands slowly until the elbows are almost straight and the towel is still taut.
• Keep the legs quiet throughout the rep so the towel tension does not swing or slacken.
• Exhale as you curl up, inhale as you lower, and reset the towel before the next rep if the grip slips.

Tips & Tricks

• Keep the towel wrapped over the arches, not just the toes, so it does not slide when you curl harder.
• If your shoulders start to lift, lower the tension and keep the back of the upper arms closer to the floor.
• Use a slow 2-3 second lower to keep the biceps under tension instead of dropping the hands quickly.
• Hold the wrists in line with the forearms; letting them cock back turns the set into a grip exercise too soon.
• The elbows should stay near your sides. If they drift forward, shorten the curl slightly and reset your shoulder position.
• Match both sides evenly. One hand should not pull harder than the other or the towel will twist and change the resistance.
• If the towel feels too easy, pull a little harder through the feet or slow the return phase before changing anything else.
• Stop the set when the knees start to wobble or the torso starts to arch, because those are the first signs the curl is getting sloppy.

Frequently Asked Questions

What does Lying Double Legs Biceps Curl With Towel work most?

The main target is the biceps, with the brachialis, brachioradialis, and forearm flexors helping to keep the curl tight and controlled.

How do I set up the towel for Lying Double Legs Biceps Curl With Towel?

Lie on your back, bend both knees, and loop the towel around both feet or under the arches. Hold the ends in each hand with your palms up and elbows tucked close to your sides.

Should my feet move during the curl?

No. The feet and knees should stay fixed while your hands do the curling, otherwise the towel tension changes and the biceps lose the work.

Why do my shoulders want to lift off the floor?

That usually means you are pulling too hard or losing shoulder position. Ease off the tension and keep the back of the upper arms and shoulders heavy on the floor.

Can beginners do Lying Double Legs Biceps Curl With Towel?

Yes. Start with light towel tension and small, controlled reps so you can keep the elbows tucked and the wrists straight.

What is the most common mistake in this exercise?

Letting the towel go slack or letting the elbows drift forward. Both mistakes reduce biceps tension and turn the movement into a loose tug.

How can I make Lying Double Legs Biceps Curl With Towel harder?

Pull more firmly against the towel, slow the lowering phase, or keep the curl strict for more reps before you rest. You can also shorten the towel less so the tension starts earlier.

Is this more of a strength exercise or an endurance exercise?

It works well for both, but the self-resisted setup usually fits higher-rep accessory work and controlled arm endurance better than maximal strength work.
