DAY UPPER-BODY WORKOUT
This workout kicks off with two mobility drills to improve your flexibility for the moves ahead. The rest of the exercises use a variety of holds to help you build strength across your upper body and core. As you progress through the four-week plan the time under tension increases, meaning your muscles will be working harder for longer and as a result grow back bigger to handle
the increased workload. Forget about how much you can bench – how long you can hold an L-sit is far more impressive.
