"The transverse abdominal muscles help to stabilize the pelvis when running," Tamir says. This muscle-strengthening exercise, the dead bug knee-to-elbow, is excellent.
The glute bridge march works not just the glutes and hamstrings, but also the deep muscles of the lower back (multifidus) and, to a lesser extent, the transverse abdominals.
By extending the lever, the forearm plank walk-back increases the difficulty of a standard plank and strengthens the transverse abdominals and the multifidus.
The adductor muscles connected to the hip joint are strengthened in the Copenhagen plank, which also helps to strengthen the obliques.
"Sitting for long periods of time can cause the hip flexors to tense, which can force the pelvis forward. "This causes your abdominal muscles to disengage and strains your lower back."
