Side plank hold

How to do it

1. Lie on your side, then press up onto one straight arm, hand planted under your shoulder, and stack your feet so your body forms a straight line from head to heels.
2. Reach your top arm straight up toward the ceiling and hold.
3. Your whole side - from shoulder to obliques to hip - works to keep that line from bending, and gravity spends the entire hold trying to fold you in the middle.
4. Complete the hold, then switch sides.
