The Marching Hip Lift is a good bridging exercise between doing a standard 2 Leg Hip Lift and progressing to a 1 Leg Hip Lift Version.
It will put a lot of work through the hamstrings (muscles at the back of the leg) whilst forcing you to keep the butt and core muscles braced hard so the hips do not drop from side to side as you march.
• Lay with back on floor, knees bent 90 degrees with heels on a bench. Arms positions 45 degrees to body with palms facing up.
• Squeeze shoulder blades down and together and brace abdominals.
• Heels should be close to edge of a bench and calves should not be on bench.
• Press heels down hard into bench whilst squeezing butt muscles hard to raise hips up off floor
• Continue raising hips up until knees - hips - shoulders are in a straight line.
• In this position, lift one foot up off the bench until knee is 90 degrees to same side hips
• Then return the foot to the bench and repeat with the other leg
