I did 12-minute reverse planks every day for a week — here's my results

If you haven’t seen the reverse plank before, flip a traditional straight-arm or forearm plank over, and you’ve nailed it.

Like many plank variations, this move targets your core, namely the rectus abdominis or “six-pack” muscles, shoulders, arms, back, glutes, and legs. And like most of our challenges at Tom’s Guide, you shouldn’t overtrain one muscle group or one exercise every day, so remember to give yourself ample recovery time if you practice planks.
