For anyone wanting to push a little bit further and reach higher, find a type of HIIT exercise that you enjoy doing regularly.
High intensity Interval Training (HIIT) involves short bursts of intense exercise alternated with low-intensity recovery periods. A good guideline is to strive for 70 to 90 percent of your maximal heart rate during the high intensity periods and 60 percent of your maximal heart rate during the recovery periods.
High intensity gym classes and boot camps are other popular options when you want to push your fitness goals higher.
Outside of the gym, other examples of HIIT exercises you can do include mountain biking, hill sprints, and circuit training.
