An isometric workout is strength training in which the joint angle and muscle length do not change during contraction. An isometric strength exercise is typically performed against an immovable object. Do pushups and hold for 30 seconds, followed by hip thrust hold and squat or split squat (or both) hold. Do each of these for 15 or 30 seconds. And repeat the whole session three of four more times.
