2nd Day of Fitness
2 x Mountain Climbers
Drop to a top press-up position, with your arms straight and legs extended and supporting your weight on your hands and toes. Keeping your core engaged, bring one knee towards your chest, then return it to the starting position. Repeat the movement with your other leg, then continue
Put your hands on a bench or other raised surface. This forces your legs to take more of your bodyweight.
Rest your hands on an uneven surface such as a gym ball, or by bringing your right leg out and right knee towards your right elbow for Spider-Man Mountain Climbers.
