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.

Bent knee leg raises strengthen the lower abs. Lie on your back, knees bent, lift them towards the chest, then lower slowly. Improves core stability and tone.

Knee push-ups are a modified, less intense version of the classic push-up, making them accessible for beginners or those with physical limitations.

The barbell squat targets quads, hamstrings, and glutes. Place a barbell on your upper back, squat deep with your hips back, and stand up straight. Builds lower body strength and stability.
