Spiderman Plank Crunch
The Spiderman crunch adds knee-to-elbow drives to a forearm plank, engaging the obliques while your core keeps the rest of you locked in a straight line. The dynamic motion builds stability and side-of-waist strength together. A good way to make planks more demanding.
How to do it
- 1
Set up in a forearm plank with elbows under your shoulders and a straight line from heels to shoulders.
- 2
Keep your body rigid as you bend one knee up toward the same-side elbow.
- 3
Return that leg to the start without letting your hips drop.
- 4
Repeat with the other knee.
- 5
Alternate sides for the duration of the set.
