Diamond Push-Ups on Knees focus on the triceps, inner pecs (chest), and shoulders while reducing load for beginners or those needing modification. Start in a plank position on your knees with hands close together under your chest, forming a diamond shape with your fingers. Lower your body toward the floor, keeping elbows close to your sides, then press back up to full arm extension. Maintain a tight core and controlled movement. Gymcheq ensures proper alignment and technique for effective pecs (chest) and triceps engagement.
