4-Week HIIT Workout

High-Intensity Interval Training, or HIIT, refers to shorter exercises (between 15 and 30 minutes) that alternate bursts of high-intensity, full-energy movement with brief recovery periods.

Fitness beginners benefit greatly from HIIT workouts because they are short and simple to include in regular routines. If you’re not used to putting aside time for the gym, then you have the flexibility to whizz through a short 15-minute HIIT session and, with consistency, will still see great results.
