Nicolas Collas
Personal Trainer · Running Coach
My name is Nicolas Collas. I'm the founder of [æktiv], self-employed for over 10 years and active as a coach for 18 years. personaltrainer-basel.ch is the extension of my main site aektiv.ch — focused on running coaching and health-oriented personal training in the Basel region.
My approach combines athletic goal-orientation with a therapeutic understanding. That means: I don't just look at performance, pace or kilometres, but also at movement quality, load capacity, discomfort and your personal conditions.
Whether you're just starting to jog, coming back from an injury, want to lose weight or improve your running performance — I support you with training that fits you.

Personal coaching
I listen, observe closely and adapt the training to you — not the other way around.
The training approach
We look at your goals, discomfort, movement patterns and current fitness.
You receive a training plan that fits your body, your daily life and your goal.
I coach you personally during training, correct technique and continuously adjust the load.
The goal isn't short-term overload, but long-term health, fitness and performance.
Progress

Training goal finder

Pick a goal to see a recommendation.
Discomfort compass
Pick an area — you'll get a serious note on how we handle it in training.
Note: not a medical diagnosis. For acute symptoms, a medical or therapeutic assessment is recommended.
Basel region
The Basel region offers ideal conditions for varied run training — from the Rhine through parks and forest trails to targeted interval and technique sessions on suitable routes. Training takes place where it makes sense for you: outside, in the studio, on running routes or at an agreed meeting point in and around Basel.
