If you’re a follower of fitness trends, you’ve definitely heard the acronym HIIT being used on Instagram pages or YouTube accounts, referencing the newest way to work out. But what the heck is it?
Short for high-intensity interval training, HIIT involves quick circuits of body weight movements with little rest in between. The idea behind the craze is keeping an increased heart rate for several minutes, which helps to burn fat fast.
Though they seem daunting and don’t make for an easy workout, HIIT circuits are ideal for busy people on a weight loss journey. They’re quick but effective.
