Here is Friday Fast Fitness - strengthen inner legs, thighs, arms, and core, while practicing neutral spine with a friend. More exercise than putting hands up on a bench or exercise ball.
My students Johanna (1) and Diana (2) demonstrate the beginning of this move. Description of how to progress follows the photos:
- Partner 1 lies face up with bent knees
- Partner 2 does pushups on Partner 1's knees while holding neutral spine, not letting the lower back sag and arch downward. Partner 1 gets entry-level exercise hip and core exercise by holding legs stable and does not let knees wobble. Higher-level exercise is described below the photos.
- Switch and repeat.



To increase core and hip stabilization training for both partners, Partner 1 tilts knees slightly to each side while Partner 2 continues pushups. Try both moving continuously side to side, and holding legs stable at an angle. Do not twist your spine.
Have fun moving and laughing with a partner.
