Centr Team

This tutorial covers every exercise you'll be doing on day 5 across the three weeks of phase 1. It is split into Key lifts – compound movements that repeat each week – and Supporting exercises that will change each week.

Key lifts

Nail the big compound lifts that will be repeated on day 5 each week.

Bent-over wide row

Target: Back, lats, rhomboids, rear deltoids

  • If you're in the early stages of building the strength in your back, you can rotate your shoulders closer to your body and take each side at a time.

Modification – Dumbbell incline lateral raise:

  • If you tend to start using momentum, switch to an incline raise.
