Editor's Pick: If your calf muscles get stiff from sitting all day, standing on this slant board for a gentle stretch really helps open up the Achilles tendon and calf muscles. The angles range from 15° to 45° across five settings—start with a lower angle and gradually raise it, without feeling too intense. The anti-slip texture on the bottom grips well, so you won't wobble even while doing a single-leg calf stretch. It weighs just 3.7 lbs [1.68 kg], so you can toss it in your gym bag. In the office, lean it against the wall during lunch break for a quick stretch, making your afternoon walks noticeably easier.
