I started with Flavio 6 months ago with a horrible limp and a bad knee injury. I'm now running around on the tennis court and having a great time. I can't recommend this place highly enough.
Absolutely the best personal trainer I have been to. A tailored program has taken away any pain I had while running within 2 weeks, while pushing me harder than I have been in a gym scenario for a long time.
Check these guys out.
