No equipment needed: Your body weight is enough to strengthen and tone muscles. Burn fat faster: HIIT is known to help reduce body fat while maintaining lean muscle. Can be modified: Perfect for beginners, intermediate users, or advanced athletes. Boosts overall fitness: Improves strength, endurance, coordination, and cardiovascular health. 🕒 The 20-Minute Full-Body HIIT Workout (No Equipment) This workout includes: Warm-up – 3 minutes Main HIIT circuit – 14 minutes (7 moves × 2 rounds) Cool-down – 3 minutes Each exercise is 40 seconds ON, followed by 20 seconds REST. 🔥 Warm-Up (3 Minutes) Before jumping into intense intervals, wake up your muscles and joints.
