Bodyweight squats are a versatile exercise targeting the quads, hamstrings, glutes, and core. Stand with feet shoulder-width, squat down, keeping your back straight, then rise. Ideal for strength, flexibility, and can be done anywhere, no equipment needed.

Mountain climbers combine cardio and strength, targeting the core, legs, and arms. Start in a plank, alternate driving knees towards the chest. Fast-paced, boosts metabolism.
