Many celebrities have jumped on the HIIT bandwagon and it is no surprise really, the results that come from this form of training are clear to see on social media. If you’re looking to tone up, get lean or just shed some pounds, HIIT is the way to go. It’s not easy by any means and it can take some time for your body to get used to, but you will see a difference quickly, especially if you back it up with healthy eating. High-intensity training is all about pushing your body to the max, having a short break and then hitting it hard again. Exercises can include squats, burpees, press-ups, sit-ups, crunches, high knees and star-jumps to name a few. As an example, a session may include 4 sets of press up burpees, 4 sets of high knees, 4 sets of lunges, 4 sets of crunches and 4 sets of pull-ups.
