An element of Jason's services that seems underrepresented here is the fact that he offers clients the option of training with his colleagues. In my case, Jason quickly sized up my needs and matched me with James Balazs (pronounced like ""ballast"" without the ""t""), who works out of the Easton Gym on the 3rd Street Promenade in Santa Monica. I've worked out with James for more than a year -- starting at age 53 and 40 pounds overweight -- and with his careful guidance have dropped my BP from dangerous to normal, my body-fat percentage from obese to normal, my weight from 250 to 214, my strength and well-being from lousy to good. James is a knowledgeable trainer, not some rep-counting moron who doesn't understand customizing workouts (of which there are far too many in this field). He's sensitive to clients' changing needs, never appears bored, is extremely attentive to correct form and keeps workouts varied. Plus, he's a genuinely good, honest, funny and communicable guy. Highest recommendation.
Pros: A real pro.
