H.I.R.T.

High-Intensity Resistance Training (H.I.R.T.) is a fast-paced, sets and reps based workout. A mixture of plyometrics, callisthenics, weight resistance, and static movements are completed in succession making up a set of exercises which is followed by a short rest and repeated. If you're after an intense, number focused, and somewhat self-driven workout, this is the one for you.
