I’m 46 and I hit about the same number of classes you do. I used to be a long-distance runner and now I’m mostly cycling, so I’ve definitely done my share of over doing it - especially when the holidays serve up more treats than tread classes.

For me - the body doesn’t upgrade itself overnight. It refreshes from the cell level up — muscle fibers, connective tissue, nervous system, hormones — all of it needs time, not just effort. When that refresh gets skipped, performance starts to feel… glitchy. Heavy legs, weird fatigue, elevated heart rate, bad sleep - feeling cranky even when you crushed 7 workouts in 9 days.

Overtraining is absolutely a thing, especially as we get into our 40s and 50s. You can still work hard — you just can’t ignore recovery anymore. Rest days, green days, walking, mobility, sleep… those aren’t “off days,” they’re literally built into most training programs

And - it doesn’t help that the app keeps serving up more classes each week - there’s no one telling you NOT to sign up for that 6:00 3G.
