Common Mistakes in HIIT

1. Skipping the Warm-Up

Why It Matters: A proper warm-up prepares your body for the intensive movements of HIIT and reduces the risk of injury.

What to Do: Spend at least 5 minutes warming up. Include dynamic stretches like arm circles, leg swings, and high knees.

2. Poor Form During Exercises

Why It Matters: Compromising your form to keep up with the pace can lead to injuries and ineffective workouts.

What to Do: Focus on quality over quantity. For instance, during burpees:

• Step-by-Step:
  1. Start standing tall.
  2. Drop into a squat, placing hands on the ground.
  3. Jump feet back into a plank.
  4. Perform a push-up (optional).
  5. Jump feet back to hands, then explosively jump up.
• Form Cue: Keep your back straight during the plank position.
• Common Mistake: Letting your hips sag during the plank. Fix by engaging your glutes.

3. Inadequate Recovery Between Intervals

Why It Matters: Insufficient rest can compromise your performance and lead to burnout.

What to Do: Implement structured rest periods. Aim for 30-60 seconds of rest after each high-intensity interval.

4. Not Tracking Progress

Why It Matters: Without tracking, it’s challenging to measure improvements and set realistic goals.

What to Do: Keep a workout journal or use apps to log your workouts, including time, reps, and how you felt.

5. Lacking Variation in Workouts

Why It Matters: Repeating the same routine can lead to plateaus and decreased motivation.

What to Do: Incorporate various exercises and formats. For example, alternate between:

• Burpees, mountain climbers, jump squats, and high knees.
• Change the duration of intervals: 20 seconds on, 40 seconds off one day, then 30 seconds on, 30 seconds off the next.
