Planks are a great full body strength exercise! Take note of these common mistakes to get the most out of your planks (and avoid injury!).
1. INACTIVE LEGS
While practicing plank, it's easy to lose activation in the legs. Try your planks with the FLXBall under the tops of your feet, it will make it impossible to forget to activate the legs!
2. SUNKEN SHOULDERS
If you tend to drop in the shoulders, practice your planks with the foam of the Flexistretcher around your shoulder blades. Dropping in the shoulders can cause unnecessary tension in the upper back!
3. LOWERED HIPS
When the abs become fatigued it's easy to let the hips dip low. Always be sure to keep the hips in line with the body (otherwise you can injure your lower back!). If full plank is too much pressure, practice with your knees lowered to the ground!
