RUGBY OFF-SEASON: SIZE GAINER

Accelerate Coaching

Rugby
Coach
Ed Miles ASCC

Rugby is a sport that demands peak physicality — power, speed, endurance, and resilience. The off-season is a crucial window for players to build serious muscle mass, correct imbalances, and return to the pitch bigger, stronger, and more dominant than ever. "Size Gainer" is a specialized, high-performance off-season muscle-building programme designed specifically for rugby athletes. It’s not a generic gym plan — it’s built by rugby coaches and sports scientists to translate directly into on-field performance.
