ABS RUNNER

MUSCLES WORKED: ABS, LOWER BACK, GLUTES, SHOULDERS

Your heart rate should be high, so shift back to some abs work. Return to the press-up position. Keeping your core tight, slide your right leg forward, driving your knee towards your chest. Return to the press-up position and repeat on the other side. Repeat the pattern until your time’s up. No sand nearby? Try some mountain climbers here instead.
