Sustain Performance is a strength and movement coaching practice based in Battersea, SW11, working with professionals across South West London and online with clients globally.

In-person sessions take place at a private training facility in Battersea — easily accessible from Wandsworth, Clapham, Balham, Tooting, Putney, and throughout SW London. For clients outside the area, the full Sustain Performance system is available online, with coaching delivered to clients across the UK, Europe, and worldwide.

Who trains here

The majority of clients who find Sustain Performance aren't looking for a gym. They're looking for a system. Most arrive through pain or injury — back pain, sciatica, a disc issue, post-surgical recovery, or a persistent niggle that physio alone hasn't resolved. Others come having outgrown generic programming and wanting something structured, progressive, and properly coached.

They're typically professionals — working in finance, property, tech, law, or running their own businesses. Time-poor, intelligent, and done with approaches that don't deliver. They want to understand their training, not just follow instructions.

What's available in Battersea and SW London

Back Performance System — In-Person A structured four-phase programme for people dealing with back pain, injury, or post-surgical recovery. Delivered in person at the Battersea facility. Phases run from pain reduction and stability through to full strength and performance. Clients travel from across SW London — Wandsworth, Clapham, Balham, Tooting, Putney — to train here.

Sustain Performance — In-Person Long-term strength and conditioning coaching for professionals who want a system that fits their life. Progressive, evidence-led, RPE-regulated. Three strength sessions and one to two conditioning sessions per week. In-person at the Battersea facility.

Online Coaching — Worldwide Both programmes are available fully online for clients who cannot train in person. The same structured methodology, the same level of coaching, delivered remotely. Current online clients are based across the UK, Europe, and internationally.

Why professionals in SW London choose Sustain Performance

Generic personal training is widely available in Wandsworth, Clapham, Balham, and across SW London. What isn't widely available is a coaching practice that integrates strength training with injury rehabilitation, operates from an evidence base, and explains the reasoning behind every decision.

Ollie Weguelin has 12 years of coaching experience and has personally undergone two spinal surgeries — giving him a level of understanding of pain, injury, and the psychological impact of physical setback that most coaches don't have. He contributes regularly to the Sunday Times, GQ, Esquire, and Women's Health on strength, movement, and injury science.

Clients don't come here for a quick fix. They come because they want something that lasts.
