The story
About RungGym
RungGym was not dreamed up in a meeting room. It grew out of the work of a personal trainer who spent every week typing out plans.
I am Lukas, a personal trainer in Ghent, Belgium. I program my own clients with RungGym every week, and every plan the engine writes is one I would hand to a client myself. Every dosing rule points to the ACSM or NSCA source it came from. Questions go to me directly: info@runggym.com.
Why this tool exists
Every client has a goal, a level, an injury history and their own equipment. Writing a considered block for each one takes an hour, and it comes around again every few weeks, for every client.
Most trainers cope with one standard plan, lightly tweaked. That works until a client with knee complaints gets the same lunges as everyone else. RungGym starts from the opposite end: the rules are fixed and built on evidence, the content differs per client.
Our principles
- 01
Source over gut feeling. Every dosage rule for sets, reps, rest and progression points to a concrete source (ACSM, NSCA, published research). Where there is no hard source, we say it is generally accepted practice instead of selling it as proven.
- 02
Safety is not a checkbox. Injury exclusions sit at the core of the selection, not as a warning afterwards. An exercise that is advised against simply never enters the plan.
- 03
Honest about limits. Pick a frequency below the ACSM recommendation and RungGym will still generate the plan, but with an explicit note. You know your client better than an algorithm does.
- 04
The trainer stays the coach. RungGym writes the plan; you judge it, adjust where needed and guide the execution. The software does not replace expertise, it saves typing.
Where we stand
RungGym is a young product. Every exercise in the training engine carries its muscle groups, equipment, variant family, execution cue, injury exclusions and source references. The client portal shipped: your client opens their own worksheet from a private link and logs what they lifted. Next up: more exercises and finer periodisation, driven by trainer feedback. Run into something? Let us know, that's the fastest way to improve it.
