The Ab Flexor Kick is surprisingly difficult, and is an excellent addition to your six-pack repertoire. Though your arms will support you the entire time – keeping your back safe – the demand placed on your abdominals and hip flexors is significant. The Fitness Camp features the Ab Flexor Kick in many of its online personal training workouts.
