Questions, answered.
How much does it cost?
Training at BTX is priced as a membership, not per session, because lasting results need a programme rather than drop in workouts. We match the plan to your goals on your free strategy call. Most clients train 2 to 4 sessions a week.
Is this for beginners, or do I need to be fit already?
Yes, BTX is for beginners. We start from your baseline, whatever that is, and build from there with proper technique, progressive programming and full coaching support from day 1.
How long until I see results?
Most clients see measurable changes in body composition within 4 to 6 weeks of following their programme consistently. We check it with an InBody 770 rescan every 4 weeks.
Do you work with people with health conditions?
Yes. We work with clients managing type 2 diabetes, hypothyroidism, osteoporosis, high blood pressure, cardiac conditions and recovery after surgery. Every clinical case at BTX is reviewed with Dr Matt Milner, A&E consultant and our in-house physician. He oversees blood work, interprets results in the context of your training, and liaises directly with your GP or specialist where appropriate.
What happens on the free strategy call?
It’s a free 15 minute conversation with a BTX coach about your training history, health, goals and schedule. You leave with a clear next step, and there is no sales pressure.
