Calisthenics is bodyweight mastery, developing strength, control, and athleticism using your own body as the resistance. At BTX, calisthenics training is integrated with strength and conditioning work to build functional athletes, not just gym goers.
Calisthenics
Calisthenics uses bodyweight exercises, from fundamental movements like push ups and pull ups to advanced skills like muscle ups, handstands, and L sits, to build a physique that’s as capable as it looks. It demands relative strength (strength relative to bodyweight), joint stability, and movement intelligence.
Calisthenics
Mariyan Voykov, BTX Senior Coach with over 10 years in the fitness industry, has developed a deep passion for calisthenics alongside powerlifting and functional training. His approach combines the mobility and body control of calisthenics with the strength foundations of barbell and dumbbell training, creating athletes who move well and perform at every level.
Calisthenics at BTX suits clients who want to improve body control and coordination, athletes looking to complement their sport specific training, and anyone who wants to develop serious functional strength without relying solely on equipment.
Our studio at 529a Finchley Road, NW3 is equipped for both calisthenics and full strength training, giving you access to the full spectrum of movement based coaching in one environment.
Why BTX?
Lasting change needs a programme, not drop in workouts. Everything at BTX is built around your data, your schedule and a coach who is with you for every rep.
How it works
15 minutes with a BTX coach to talk through your training history, health, goals and schedule. No sales pressure.
Your InBody 770 scan measures body fat, skeletal muscle and metabolic rate, alongside a full movement assessment.
Periodised training and realistic nutrition, with a rescan every 4 weeks, so progress is measured, not guessed.

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.
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.
No. We don’t prescribe restrictive meal plans. Your nutrition is built around your lifestyle, food preferences and schedule, so it lasts beyond the 12 weeks.
We regularly work with clients managing type 2 diabetes, hypothyroidism, osteoporosis, high blood pressure and recovery after surgery, following NHS physical activity guidance. We liaise with your GP or specialist where appropriate.
