On a single leg, the following are the actions that need to be taken in order to do a hamstring bridge:
Place yourself in a supine position with your legs bent and your hips evenly spaced apart. On the mat that is piled beneath your knees, place your feet in a flat position. One of your legs should be allowed to reach all the way up to the ceiling.
You should assume a bridge position by lifting your hips off the mat and pressing your glutes at the same time.
The hips should be lowered and raised for the required number of repetitions, and then the exercise should be repeated on the opposing side. Maintain a constant level of activity in your core muscles and ensure that your hips are steady from side to side.
