Knee pushups are a beginner-friendly variation of the standard pushup. Begin by positioning yourself on your hands and knees with your palms placed shoulder-width apart. Keep your body in a straight line from your head to your knees. Lower your chest towards the floor by bending your elbows while keeping them tucked close to your body. Press back up to the starting position. This exercise helps build strength in the chest, shoulders, and triceps while reducing the load typically placed on the core and lower body.
