This is an 8-week aerobic base building program with three modality variations — running, cycling, and low-impact (rowing, elliptical, or swimming). All three follow the same weekly structure and progression logic. The goal is building the aerobic foundation that supports everything else — more mitochondria, better fat oxidation, improved cardiac efficiency, and faster recovery from all types of training. Pick the modality that fits your body, your access, and your preferences. The programming adapts.

This is a 4-day upper/lower split designed for progressive overload. It comes in three equipment variations — barbell (full gym), bodyweight (home or hotel, zero equipment), and dumbbell-only (home gym or limited facility). All three follow the same weekly structure, the same movement patterns, and the same progression logic. Pick the version that matches your equipment. Switch between them when you travel or change gyms. The programming works regardless of the tools.
