fit20 Rosedale is looking for a part time Personal Trainer to join our team

fit20 is a personal training facility. We train our clients in a small studio, on appointment, 20 minutes per week. We use an innovative and research backed training method. Our mission is to improve the quality of life of our clients by adding strength.

Our training is based on High Intensity Strength Training. Research learns that this type of training gives clients an improved strength and fitness level, boosts the immune system, gives a higher bone density and lowers the risk of chronic diseases like Diabetes or arthritis.

Fit20 clients are often busy people. They have a full time job and a family, work in the area and the 20 minute set up suits them. Also people who don’t like big, crowded gyms, people with injuries and/or chronic diseases and seniors often like to train with us. In general we see clients from all age groups, there is no age limit, but often clients above the age of 30.

As a fit20 personal trainer your main job is to adapt the training to the clients needs and personal level. You are making sure that the client makes the most out of the training for maximum results. You correct their posture and technique to keep the clients training in a safe manner. You keep track of training results and the clients progress in our fit20 trainers app.
