Incorporate HIIT (High-Intensity Interval Training) by alternating short bursts of intense exercise with brief recovery periods. Start with a warm-up, then perform high-intensity exercises like sprints, burpees, or jump squats for 20-30 seconds, followed by 10-20 seconds of rest. Repeat this cycle for 15-30 minutes, then cool down. HIIT can be added to existing routines or done standalone, offering efficient workouts with benefits for cardiovascular health, calorie burn, and metabolism.
