How to do the Lying Froggy Crunch
Lie on your back on a comfortable surface, with your hands extended by your sides or behind your head for support (not shown in images).
Bend your knees out to the sides with your soles touching each other in a "frog" position; this will be your starting position.
Engage your core and lift your shoulders and upper back off the ground, performing a crunch movement. As you crunch, push your lower back into the floor to avoid straining.
Squeeze your abdominal muscles at the top of the contraction, keeping your legs stationary and maintaining the "frog" position.
Slowly lower your upper body back to the starting position, controlling the movement with your abs.
Repeat the movement for the desired number of repetitions and sets.
Remember to breathe out as you crunch up and breathe in as you return to the starting position. Keep the movement controlled and avoid using momentum to lift your upper body.
