1. Skipping the Warm-Up

Mistake: Many beginners jump right into HIIT without warming up, increasing the risk of injury.
Solution: Spend 5 minutes warming up with dynamic stretches like arm circles, leg swings, and high knees to prepare your muscles.

Warm-Up Routine (5 Minutes)

• Arm Circles: 30 seconds (15 seconds each direction)
• Leg Swings: 30 seconds (15 seconds each leg)

2. Poor Form

Mistake: In the heat of HIIT, maintaining proper form often takes a back seat.
Solution: Focus on quality over quantity. Aim for controlled movements and remember to engage your core.

Form Breakdown (Example: Squat)

1. Stand with feet shoulder-width apart.
2. Keep your chest up and shoulders back.
3. Lower your body as if sitting in a chair.
4. Knees should track over toes, not extend past them.
5. Push through your heels to return to standing.

3. Ignoring Rest Intervals

Mistake: Beginners often underestimate the importance of rest intervals.
Solution: Stick to a structured work-to-rest ratio, such as 30 seconds of work followed by 30 seconds of rest.

Example HIIT Workout

| Exercise | Duration | Sets | Rest | Form Cue | Modification | |----------------------|----------|------|-------|-------------------------------|-----------------------| | Jumping Jacks | 30 sec | 3 | 30 sec| Land softly, keep knees bent | Step side to side | | Bodyweight Squats | 30 sec | 3 | 30 sec| Chest up, push through heels | Reduce depth | | Mountain Climbers | 30 sec | 3 | 30 sec| Drive knees towards chest | Slow down the tempo | | Plank | 30 sec | 3 | 30 sec| Keep body straight, squeeze glutes| Drop to knees |

4. Overtraining

Mistake: Many beginners are eager to see results and push too hard too soon.
Solution: Incorporate rest days to allow your body to recover. Aim for 2-3 HIIT sessions per week.

5. Not Tracking Progress

Mistake: Skipping the assessment of performance can stall progress.
Solution: Keep a workout journal to track your reps, sets, and improvements over time.

6. Lack of Variety

Mistake: Repeating the same workout can lead to boredom and plateaus.
Solution: Mix up your exercises and intervals to keep things fresh.

7. Forgetting the Cool-Down

Mistake: Ending a session abruptly can lead to soreness.
Solution: Spend 3-5 minutes cooling down with stretches to promote recovery.

• Standing Quad Stretch: 30 seconds each leg
• Hamstring Stretch: 30 seconds
• Chest Opener: 30 seconds
• Child's Pose: 1 minute

8. Setting Unrealistic Expectations

Mistake: Expecting to see results overnight can lead to disappointment.
Solution: Set achievable goals and celebrate small victories along the way.

9. Neglecting Nutrition

Mistake: Many beginners overlook the role of nutrition in their fitness journey.
Solution: Focus on a balanced diet rich in whole foods to fuel your workouts.

10. Not Seeking Help

Mistake: Trying to go it alone may lead to injuries or ineffective workouts.
Solution: Consider working with a certified trainer for personalized guidance.
