To test and strengthen your balance, try a side plank with a leg raise â get into side plank position, then lift your top leg and hold for one count. Lower it and repeat, then switch sides. In addition, planks work all the muscles you need to maintain proper posture, like your back, chest, shoulders, abs, and neck.
The plank can strengthen your core, fix poor posture, and reduce lower-back pain. But as youâre hovering there, why not make the move do double duty? These five awesome plank variations provide all the benefits of the classic core-sculpting move, while also chiseling bigger arms, building a broader back, skyrocketing your heartrate, or increasing your flexibility.
