Core exercise - Knee to Chest (double leg)

Double knee to chest exercise to strengthen the muscles located in your lower back and core. This exercise is simple and requires no equipment. Simply lie on your back, flatten the lower back into the floor, keep stomach tight and bring both knees up towards your chest. Go slowly, and control the movement down.
Grab your lower legs if this feels comfortable for your lower back.
Stretch should each be maintained for 10-30 seconds.
