I train at EOS with Kristoff. Absolutely great trainer -- super smart, good guy, makes sure his clients get effective sessions. Would absolutely recommend that if you want a gym downtown Phoenix, and want to work with a trainer, go to EOS and seek out Kristoff (big dude, looks like a viking -- but don't be intimidated). I'm pretty serious about my workouts; Kristoff really is a good person to work with; demonstrates a real commitment to clients.
