How to do lying biceps curl with towel
Master the setup, range of motion, and tempo for safer, more effective reps.
Overview
This exercise uses manual resistance to build the biceps. By lying on your back, you eliminate the ability to swing your body, forcing the arms to do 100% of the work. You control the intensity by how hard you push with your leg, making it a versatile tool for home workouts or travel.
Why Use It
- Requires no gym equipment—just a towel.
- Eliminates momentum for better muscle isolation.
- Allows you to adjust resistance instantly during the set.
When to Use It
Use this as a finisher to pump the arms at the end of a workout or when you don't have access to weights.
Stats
Instructions for Proper Form
Setup
- The Position: Lie on your back with one leg bent and foot flat. Loop a towel under the other foot.
- The Grip: Hold the towel ends in one hand with your palm facing you.
- The Pin: Glue your elbow to your side and keep it pressed against the floor.
Execution
- The Curl: Pull your hand toward your shoulder while using your leg to provide resistance.
Pro Tip: The harder you push with your leg, the more your biceps have to fight—you are the weight stack.
- The Fight: Slowly lower your hand back down, resisting the push of your leg the entire way.
Coaching Cues
- Make your leg win the tug-of-war
- Pin your elbows to your ribs
- Squeeze the towel like you're trying to wring it out
Common Mistakes
- Elbow Floating: Letting the elbow lift off the floor, which uses the shoulder.
- The Lazy Leg: Not pushing hard enough with the foot.
- Short Reps: Not letting the arm fully extend at the bottom.
How to Fix It
- Elbow Floating: Imagine your elbow is bolted to the floor.
- The Lazy Leg: Push your foot away as if you're trying to straighten your leg against your hand's grip.
- Short Reps: Ensure your hand touches the floor or gets very close before starting the next rep.

FAQ
Common Questions
Can I really build muscle with a towel?
Yes. Muscle responds to tension. If you push hard with your leg, your bicep has to work just as hard as it would with a heavy dumbbell.
