My shoulder hurts on bench. What do I do today?

Let’s swap bench for landmine press today. I’ll check in Thursday. If it’s sharp or tingly, see a physio first.

FAQ

Questions, answered.

Is Pumpstak a medical app?

No. Pumpstak is a fitness coach. When something hurts, it helps you train around it safely and tells you when to see a professional. It never diagnoses.

I’m a total beginner. Is this for me?

Yes. It’s built for beginners first: a plan made for you, plain-language guidance for every machine, and no judgement when you miss a day.

When does it launch, and on what?

iPhone first; we’re building it now and the waitlist gets the beta first. (And it’s Pumpstak, no “c”.)
