Background of HIIT
High intensity interval training (HIIT) is generally performed by sprinting close to maximum capacity followed by rest. The process is repeated several times. Proponents of HIIT say that it burns more fat than steady state cardio, because the resting metabolic rate is increased after a session of HIIT, which leads to burning additional calories even after the HIIT session.
The procedure of HIIT sounds quite similar to weightlifting. If you just replace sprinting with lifting weights, all the other steps are the same. Performing a weightlifting set to failure is also considered pushing oneself to maximum capacity. People also rest in between sets. This makes me wonder why articles on HIIT always suggest sprinting and never even mention that weightlifting as a form of HIIT. Well, is it? Can weightlifting also give you the same increased RMR as well as traditional sprinting HIIT?
