4-Day Upper/Lower Strength Program

RPE — rate of perceived exertion — is the honest way to program strength work for intermediate lifters. Instead of prescribing exact percentages (which change as you get stronger or have an off day), RPE tells you how hard to push. An RPE 8 means you left 2 reps in the tank. RPE 9 means 1 left. This auto-regulates the load to your actual strength on any given day.

This program runs four days a week: Upper A on day one, Lower A on day two, a rest day, then Upper B and Lower B. You hit each lift twice a week with slightly different approaches — the A session is heavier and lower rep, the B session is more volume at a moderate intensity. This combination drives both strength and some hypertrophy.

The main lifts (squat, bench, deadlift, overhead press) are the focus. Accessory work builds the supporting muscle that keeps the main lifts healthy and growing. Do not skip the accessories — they are not optional fluff.

This program is for lifters who are no longer making progress on linear progression. If you can still add weight every session, start with the beginner program first. If your squat progress has stalled for two-plus months despite consistent training, you are ready for this structure.
