Your back should be considerably stronger today than it was at the beginning of this trainer. Having a strong back is healthy for your spine, good for your posture, and will make all of your other lifts better because your upper body will be more stable.
You're eating fewer calories this microcycle, but you'll still get plenty of the right macros to fuel these heavy workouts! The lower volume should also help you hit the prescribed lifts with max effort.
Don’t forget to add a little weight to your pull-ups so you can get the most out of each set.
