Tips for Success
- Go all out during work intervals. HIIT is only effective if you push your limits.
- Breathe deeply and recover during rest. Stay loose, not stiff.
- Hydrate well. Sweat loss is high during intense intervals.
- Form matters. It’s better to go slower with proper form than rush through with poor technique.
Frequently Asked Questions
Is HIIT safe for beginners?
Yes, but start slow. Use low-impact modifications like step-back lunges instead of jump lunges, and knee push-ups instead of full ones.
How many times per week should I do this 20 min HIIT workout?
2–4 times per week is ideal. Leave rest or active recovery days in between to let your body recover.
Can HIIT really burn fat fast?
Absolutely. HIIT increases your resting metabolic rate, helping you burn calories even after your workout is over.
Do I need to warm up and cool down?
Yes. Warming up prevents injury and improves performance. Cooling down helps you recover and reduces soreness.
Can I build muscle with this routine?
HIIT primarily improves cardiovascular fitness and endurance. For serious muscle gains, pair it with resistance training.
