HIIT High Intensity Impact Training
High-Intensity Interval Training (HIIT) is easily one of the most efficient methods of getting stronger while shredding fat. HIIT workouts generally involve short bursts of various exercises performed at high intensity while minimizing rest time in between movements. HIIT workouts speed up the body’s metabolism which aids in fat loss. Your body will actually continue to burn calories even after you have finished your workout; this is what’s known as the “afterburn effect.” The body’s demand for oxygen post-workout in order to aid in the recovery process is what leads to this phenomenon.
Although you could see some minimal muscle gains as the result of HIIT workouts, you will most definitely see an improved physique and strength gains.
