30 Days of HIIT, Day 20

Another day and another intensive workout. Let’s get started with:

  • 20 seconds of high knees
  • 20 seconds of squats
  • 20 seconds of climbers

This will really help you get super fit to play tennis at the highest levels.

Disclaimer: Do not perform these exercises if you have any injury, get rehabilitation first. If you get short of breath, feel fatigued or tired during any of these workouts, stop and take a break. Consult a doctor/trainer if necessary before starting any workout session. Children should do them under supervision of an adult.

These workouts are taken from the Darebee 30 days of HIIT program.
