Diamond Push-Ups focus on the triceps, inner pecs (chest), and shoulders. Begin in a plank position with hands close together under your chest, forming a diamond shape with your thumbs and index fingers. Lower your body toward the floor, keeping elbows tucked 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.
