You used to crush workouts. Now the same routine wrecks you for three days, you're gaining weight on less food, and every app you've tried keeps telling you to push harder.
"Struggling ALOT with the loss of fitness due to the perimenopause." — voiced in r/Perimenopause community discussions, 2026
Perimenopause changes how your body responds to training. Most of what's on the market hasn't gotten the memo.
What other apps get wrong about perimenopause
They program women as small men. Most training protocols were built and tested on young men, and the prescriptions that came out of it got handed to women with the numbers scaled down and nothing else changed.
Streak counters punish the days your body needs off. Missing a session in perimenopause isn't failure. Gamification borrowed from men's training apps trains you to override the signal that used to tell you to rest.
Cycle-syncing never worked, and now there's no cycle to sync to. Your cycle shortens, then lengthens, then skips. There's nothing left for a calendar to predict.
How Salerna programs for perimenopause
1. Strength first, and heavier than you've been told. In the LIFTMOR trial, 101 postmenopausal women did supervised high-intensity resistance and impact training twice weekly for eight months, and lumbar spine bone density rose 2.9% against a 1.2% loss in controls (Watson et al., 2018). We build toward loads you can actually progress, and we tell you where the evidence came from.
2. Intensity capped by recovery, not by fear. Cardiovascular risk climbs sharply through the transition, so dropping intensity is the wrong instinct. What changes is how much you can absorb — we extend warm-up and cool-down, lengthen rest between exercises, and pull high-intensity work entirely on days you report hot flashes, without cutting your volume or loads.
3. Joints get more say than they used to. Declining estrogen reduces collagen synthesis and slows tendon adaptation (Chidi-Ogbolu and Baar, 2019), which is why an irritable knee or shoulder becomes programming information rather than something to push through.
4. A daily check-in, not a fixed calendar. Four questions before every session: sleep, energy, soreness, stress. A poor-recovery day changes the session — it doesn't trigger a notification telling you to show up anyway.
5. Clinician-reviewed rules, and you can see them. Our advisory board reviews the condition logic and holds the authority to switch a rule off. When your session changes, you can see which input changed it.
Frequently Asked Questions
My heart rate has felt strange for weeks. Is that perimenopause?
It's more common than most women are told — about half of women in the SWAN cohort reported palpitations at a moderate or high rate, peaking during perimenopause (Carpenter et al., 2023), and this was not linked to atherosclerosis or arterial stiffness. But thyroid function and iron levels can cause the same picture and are cheap to check. If this is new and persistent, get it looked at before assuming it's training or hormones.
Should I stop doing HIIT in perimenopause?
No. Cardiovascular risk climbs through the menopause transition, which argues for keeping hard work in, not taking it out (AHA scientific statement, El Khoudary et al., 2020). Salerna adds warm-up, cool-down, and rest time around high-intensity work rather than reducing your loads or volume, and pulls it on days you report hot flashes.
How many days a week should I lift in perimenopause?
Two days a week is the floor; research on bone specifically points toward three sessions a week at 70% of one-rep max or higher, sustained for about a year (Wang et al., 2023). Salerna doesn't pick your days — you tell us how many days you want to train, and the engine programs the load progression and session content into that.
