Robo Split

Four-way body-part split — one muscle pair per day, alternating A/B weeks.

Day 1 Chest & Triceps · Day 2 Back & Biceps · Day 4 Shoulders & Lower Back · Day 6 Legs, with rest on days 3, 5 and 7. The next week runs the same split as B workouts — different variations of the same lifts (bilateral rows, Arnold press, RDLs, dips) — for a 14-day A/B cycle. Every lift pyramids 15/10/8/5 using the Arnold split's exercise pool and loading. Every non-leg day closes with one light shoulder-health set — side-lying external rotation for the rotator cuff, and push-up plus, prone Y raise or serratus punch for the shoulder blade. Together they train the muscles that keep the ball centred in the socket and the collarbone joints steady under overhead load.
