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.

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

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.

The plank is a core-strengthening exercise. Assume a push-up position, elbows under shoulders, resting on forearms. Keep body straight, hold. Enhances core stability and strength.
