Exersuisse Solothurn runs under the Kieser banner - its website points to kieser.com - and that tells you the format before you walk in: machine-based strength training, no free weights, no music, no smoothie bar. The rating is 4.7 from 66 people. One January 2025 review lays out the method so completely that I'll lean on it, because it does the describing better than I could.
What you're actually buying
That January 2025 member wrote the manual: "great strength training place. ascetic, scientific and also therapeutic approach. training solely on isolated muscle groups through machine workout, hypertrophy based. 4-2-4-2 or even superslow. progress is self monitored and also periodic checkups through electric analysis of fat/muscle mass... no free weights." They then listed what you won't find: "no bullsh1t parading of gym rats, no sh1tty music blaring, no supplement sales, no socialising drinks bar." And the trade-off in one line: "you pay more and get more than in many places." If that sounds like your kind of training, this place was built for it. If it sounds joyless, that's a real signal too.
Who it's really for
The reviews point at an older, deliberate clientele. A member from May 2026 wrote, "After 69 years of being completely inactive, I discovered Kieser because I noticed I was stumbling and even falling more often... After a year and a half, I feel significantly stronger and more confident." A February 2026 German review echoed the theme, calling it "eines der besten Trainingsorte mit vielseitigen Moeglichkeiten um die Beweglichkeit im Alter beizubehalten" - one of the best training places with varied options for keeping mobility in old age (translated from German), praising a support team that gives "klare Instruktionen" and has "den noetigen Humor" (translated from German). Strength for aging bodies is a clear use case here.
Why the rating runs high, and what it hides
A 4.7 from 66 ratings looks strong, but the sample is self-selecting in a specific way. People who want a calm, coached, machine-only routine choose Kieser on purpose, so they tend to leave satisfied. A member who wants a lively free-weights room simply won't sign up, and won't be here to lower the score. An October 2025 reviewer said it flatly: "top-notch and well-run. Not for people looking for fun and shows." So the average measures how well this format serves the people who already wanted it. That's worth remembering when you compare it to a general-purpose gym's rating.
Where the voices agree
Staff attentiveness comes up again and again. The January 2025 review noted "coaches make rounds at all times, always available, throwing in an occasional 'good work!'" An August 2023 German review praised "sehr freundliches Personal, sehr aufmerksam, schoenes sauberes aufgeraeumtes Studio" - very friendly staff, very attentive, a nice clean tidy studio (translated from German). Clean, quiet, coached - that trio repeats across languages.
What's missing
Here's the honest gap: nobody states a price. One reviewer says "you pay more," but no figure appears anywhere in the record, and Kieser is a premium format, so the cost is a genuine unknown from this page. The listed hours run early morning to evening on weekdays with shorter weekend windows, but verify them. Call +41 32 623 96 70 to confirm current pricing and a trial session.
Who it's not for
If you train with barbells, love a busy social floor, or want group classes and music, this stripped-down machine method will frustrate you. If you want isolated, supervised strength work in a quiet room, it's a strong fit.
FAQ
Does Exersuisse Solothurn have free weights?
No. A detailed reviewer states the studio trains isolated muscle groups on machines only, with a "no free weights" policy, in line with the Kieser method.
Is it good for older or deconditioned people?
Reviews strongly suggest so. Members in their late 60s describe regaining strength, balance, and confidence over a year or more.
How much does it cost?
No review lists a price, only that you "pay more" for the format. Contact the studio directly for current rates.
What's the atmosphere like?
Calm, quiet, and coached - described by one member as offering "no shows," with staff making regular rounds. Not a social or music-driven gym.
