This class is similar to Int 1 & 2. There are a few variations to keep it spicy. If you are short on time you can simply fast forward the S.I.T. rounds at the end. If you are working on body recomposition I highly recommend S.I.T. one to two times per week. I start this training block with 10s, 15s, 20s, (1) 25er, a mat, resistance band. stability ball and bench. You can do this class 2-3 times per week for 4-8 weeks. Remember there are two big goals - going to failure on each set and progressive overload over time. Have fun.
