The deload advice you've read was written for 25-year-olds. Not maliciously — the standard take-an-easy-week-every-4-to-6-weeks guidance comes from research on young, rubbery study populations. For athletes over 40, the evidence points shorter: a deload every 3, 4 weeks. Cut the training volume by 40, 50% for the week. Keep the intensity where it was.

That last part is the bit most people get backwards, so let's be exact about what a deload is. It's not a week off. It's not a week of everything-lighter. The pattern the research supports, across every discipline, is the same: cut the volume, hold the intensity. Fewer sets, shorter sessions — but the sets you keep stay heavy, and the intervals you keep stay honest. Volume is what builds. Intensity is what preserves. A deload that drops intensity isn't recovery — it's the start of detraining.

Now the honest part, because this is where most masters content gets lazy. The popular story is that older athletes suffer more "interference" between training types, or adapt worse. The research is kinder than that. A large meta-analysis tested whether age changes the interference effect between strength and endurance work — it doesn't. Masters athletes who keep training hard decline at roughly half the rate of people who stop. What changes isn't your ability to adapt. It's your recovery budget. The fatigue cost of stacked hard weeks rises after 40, the gap you need between hard sessions stretches, and adaptation lost to genuine overreaching doesn't always come back the way it did at 28. Shorter build blocks, more frequent recovery weeks. It's just what works at this age.

Two objections come up every time.

"Won't I lose fitness in an easy week?" No. The retention research here is genuinely striking — strength has held for months on a fraction of building volume, as long as the load stayed heavy. Aerobic power held for 15 weeks in reduced-training studies when intensity was protected. One week at reduced volume doesn't even register. The fatigue masking your fitness leaves; the fitness stays. That's why the week after a deload so often feels like a breakthrough. Nothing was gained that week. Something was finally allowed to show.

"But I feel great in week 3 — why stop?" Because feeling great in week 3 is the plan working, not proof it's unnecessary. Skipping deloads when training feels good is the most common failure pattern in self-coached athletes. To be honest, I'd know — my own training log has me doing exactly that, more than once. The bill doesn't arrive in week 4. It arrives three weeks later as a plateau.

The practical version: over 40, training seriously — deload every third or fourth week, cut the sets and the minutes by roughly half, keep the loads and the intervals honest, and treat the scheduled week as non-negotiable rather than something you earn by feeling broken. The athletes who last recover on schedule, not on symptoms.
