About This Event

What to expect

This Handstand Foundations workshop at Clapham Common teaches you the mechanics that actually build stability and extend your time upside down. We start with safe falling and kick-up control — the foundations most classes skip — before moving into shoulder activation and progressive drills designed to build endurance and real comfort in your handstand. Teachers: Elliott Staley Prerequisites: No previous experience required. Class is suitable for beginners to people who are trying to break the 10-15 second mark consistently.
