Why work directly with Theo?

Theo draws on 25+ years of coaching to guide each decision.

Understand the movement

If a squat becomes unstable, Theo may try a supported version or a shorter range. He uses your response to choose an appropriate starting point.

Connect mobility to strength

After assisted stretching, he may check active movement, then add a controlled exercise. The aim is to help you use the available range in training.

Progress with a reason

After travel, he may adjust the workload and observe your response before progressing. Your longer-term goal guides the work; today’s capacity determines the challenge.

Illustrative decisions; every session is planned individually.

03 / REBUILD YOUR TRAINING ROUTINE

Return to Exercise

 

For restarting after time away or an injury when exercise is appropriate. Theo chooses a manageable starting point, observes your response and builds the workload progressively, with clinical guidance when needed.

 

An early session might test control with supported movements before adding resistance. Your response helps determine the next step. The focus is rebuilding a training routine within fitness coaching, not medical rehabilitation.
