You will work for 30-seconds on each exercise so make sure you give it your all, after 10-minutes your workout will be done and dusted. 

Everybody secretly likes a shorter workout and fans of Reif's videos loved this one. One person commented, "I needed a routine like this so much! Thank you, Pam! The switch between standing ab exercises and HIIT never disappoints."

HIIT workouts have been proven in studies to improve your metabolic rate since this form of training continues to burn calories even after your done exercising. This one research paper published in the Sports Medicine journal even found that HIIT training may be able to increase your metabolism after exercise to a greater degree than resistance training or jogging can.

This doesn't mean you should drop all other forms of exercise and just complete HIIT workouts all the time. A well-rounded approach to staying fit and healthy should include variety. You're more likely to stick to your fitness goals this year if you mix it up - maybe this looks like a short burst of cardio wearing one of the best running shoes for men after a weights session. Or vice versa depending on what your training goals are.

Variety is good to have in your diet as well. You should aim to eat a mixture of quality carbs, healthy fats, plenty of fruit and vegetables, and lean protein. Protein is essential for repairing and building muscle after exercise. You can top up on this with a best protein powder for weight loss if this is something you struggle to fit into your diet.
