Workout Update: 25 Minute Speed Train: Day 43

Day 43 was the start of week 7. It switched back to upper-body to start the workout and introduced both a new tempo (4x4) and a new format. This week, you pre-fatigue the muscle group you will be working in the block with a burnout exercise, and then you do four forty-second sets of the weighted exercise. So, in the first block, you do 60 seconds of push-ups at the 4x4 tempo, and then four sets of chest presses, doing a 3x1 tempo.  In block 2, perform the arrow pulls with the bands for 60 seconds, followed by four sets of rotating rows with no tempo. In block 3, you do shoulder raise pulses with the bands for 60 seconds and then four sets of weighted lateral raises. In the final block, you do w-bicep curl pulses with the band for 60 seconds, followed by biceps curls with the 2x2 tempo. So, in each block, you do five total reps. You will be using very light weights in this workout because doing the burnout exercise at the beginning of the block instead of at the end will definitely wear you out.
