Question

explain how calisthenics can include both isometric and isotonic exercises.

Explanation:

Calisthenics uses body weight for exercise. Isotonic exercises involve muscle length change (e.g., push - ups, squats: muscles shorten/lengthen while moving). Isometric exercises involve no muscle length change (e.g., holding a plank or a wall sit: muscles contract against resistance without joint movement). In calisthenics, routines can combine moves like doing push - ups (isotonic) and then holding the push - up position (isometric), or squats (isotonic) and holding a squat (isometric), thus including both types.

Answer:

Calisthenics (body - weight exercises) includes isotonic exercises (e.g., push - ups, squats) where muscles change length during movement, and isometric exercises (e.g., planks, wall sits) where muscles contract without length change. Routines can combine these, like doing push - ups (isotonic) and holding the push - up position (isometric), or squats (isotonic) and holding a squat (isometric).
