Going to do something today I call a transitionary session by doing the first day of the week as normal. This is to avoid breaking training consistency by moving to a different routine. I ended my deload with squats so starting Westside with another day of squats will make it four days of not doing any upper body effort. This is critical because frequency is absolute key to maintaining gains on a cut, I've discovered. I can skip meals and not suffer from it but not with lifting. This is what killed my last cut. Training is clearly much more important than diet.
While I'm on the subject, another essentiality is not doing hypertrophy movements like any kind of tricep extensions, high rep curls, etc. I'm seeing success sticking to dumbbell press, push-ups, dips, and heavier curls for accessory work.
And perhaps an even more important point is to keep every session an hour or less. This has been the first time I don't go over an hour and a half, let alone one hour, and I'm profiting astoundingly.
With all that said, I'm not set on moving on just yet. If my OHP today, my weakest lift at the moment, hasn't improved and I feel stale doing another of these workouts I'll make the switch. If I feel strong then I'll keep going for another four weeks before reevaluating.
