Sport-Specific
Off-Season Engine — 16-Week Endurance Strength
Sixteen weeks of off-season strength for endurance athletes, built to sit under your own riding, running or swimming — not replace it. Three sessions a week across four phases: base, force, speed, maintenance. Every week states the sport volume it assumes and the 24-hour separation rule it needs.

About this program
A gym block for someone whose real sport happens outside the gym. Three full-body sessions a week for sixteen weeks, written from the assumption that you already have a riding, running or swimming week and that the barbell work is subordinate to it. Squatly does not prescribe your sport volume — it is yours, you own it, and every week of this program states the volume it was written against and what to do when yours is bigger.
Written for triathletes, cyclists, trail runners and open-water swimmers between seasons who want a real strength block instead of a powerlifting program with the numbers filed off. It is not an endurance plan and will not tell you how far to ride. It is also not the in-season program: once racing starts, phase four hands you to Mile Support — 2-Day Strength for Runners. If you want running and lifting planned together in one block, Road & Rack is that program, not this one.
Grounded in our Progressive Overload, Volume Management and Fatigue & Recovery frameworks. Loading is RPE-anchored and steps on a two-week clock rather than riding a percentage wave, because your own sport volume makes a stale one-rep max meaningless inside a fortnight. The strength-transfer literature in endurance sport is consistent on the shape used here: a heavy, low-volume off-season block followed by a small maintenance dose. No velocity device is required or implied — maximal concentric intent is an instruction you follow, not a number a gadget reads.
Expect three sessions a week for the whole block — the session count never drops, only the volume inside it — a competency check at week four, roughly ten to twenty percent added load on the squat and Romanian deadlift, and a final two weeks light enough to keep indefinitely.

- Weeks 1–460Intensity
Phase 1 · Standard
Build the Base
Four weeks at three sets of eight to twelve, RPE 6-7. Positions, single-leg control and trunk bracing, with a competency check at the end of week four.
- Weeks 5–1062Intensity
Phase 2 · Accumulation
Build the Force
Six weeks from four sets of six to four sets of four, RPE 7 up to 8, every working rep driven with maximal intended speed on the way up.
- Weeks 11–1482Intensity
Phase 3 · Intensification
Make It Fast
Four weeks of three heavy sets of three to five plus two or three explosive singles, while total lifting volume falls to make room for rising sport volume.
- Weeks 15–1635Intensity
Phase 4 · Transition
Keep It
Two weeks at two sets per pattern with load held — the maintenance dose you keep running once the season starts.
