Performing the: A Step-by-Step Tutorial Single Leg Sliding Floor Bridge Curl on Towel
Lift the foot without the towel off the floor, keeping your knee bent at a 90-degree angle, and push the other foot into the towel while lifting your hips off the floor into a bridge position.
Slowly slide the foot on the towel away from your body, straightening the leg while keeping your hips elevated.
Then, use your hamstring to pull the towel back towards your body, returning to the bridge position.
Lower your hips back to the floor to complete one repetition, and then repeat the exercise with the other leg.
