Plank variations have several benefits, one being that they are a brilliant compound exercise, working most of the muscles in your body. Unlike crunches, they don’t put any pressure on your lower back, so you’ll often find planks in most of the best ab workouts out there.
Plank toe taps are an excellent plank variation as they activate the external and internal oblique muscles, the rectus abdominis (the top layer of your abdominals, often referred to as the ‘six pack’), and the transverse abdominis (the deep core muscles).
