Frequently Asked Questions
The Assessment Session is a one-on-one appointment with one of our coaches at the studio. It’s the starting point for anyone looking to train at CLIENTEL3. During this session, we take the time to understand your body, lifestyle, and goals, while also evaluating your movement through a series of foundational exercises. It’s not a workout, it’s a personalized evaluation designed to set you up for long-term success.
The Assessment Session costs $50. Before booking, we require a brief pre-screening call (10–15 minutes). During this call, we’ll answer any initial questions and get a sense of whether CLIENTEL3 is the right fit for your needs.
If, during the call, we determine we are not a good match, we’ll refund the $50.
