⚡ Pro Training Tips
- Focus on form first, speed second. A controlled burpee beats a sloppy fast one every time.
- If you cannot talk in short sentences during work intervals, you are at the right intensity.
- Hydrate well before the workout — sipping water during rest periods helps, but do not chug.
- Track your reps each round. Trying to beat your own numbers is a great motivator.
- Do this workout 2–3 times per week with at least one rest day between sessions.
Frequently Asked Questions
Is HIIT good for beginners?
Yes, as long as you modify exercises to match your fitness level. Use the beginner modifications listed for each exercise and focus on maintaining good form rather than speed.
How many calories does a 20-minute HIIT workout burn?
Depending on your body weight and intensity, expect to burn 200–350 calories during the workout plus additional calories for hours after due to the afterburn effect (EPOC).
Can I do HIIT every day?
It is not recommended. HIIT is taxing on your nervous system and muscles. Aim for 2–4 sessions per week with rest or low-intensity days in between for recovery.
What should I eat before a HIIT workout?
A small meal with carbs and protein 1–2 hours before works best. Think a banana with peanut butter, oatmeal, or a small smoothie. Avoid heavy meals right before training.
