The plank strengthens the abdominals, back and shoulders. Muscles involved in the front plank include: Primary muscles: erector spinae, rectus abdominis (abs), and transverse abdominis.
- Get into a tabletop position with your shoulders directly over your wrists and hips in line with your knees.
- Engaging your abs, shoulders, back, and glutes, extend your legs back to straighten into a plank and hold.
- If you can, do the exercise in front of a mirror, to check that your butt isn’t raised. (A common mistake, but your body should be flat as opposed to an upside down-V shape.)
