Yorba Linda Fit Body Boot Camp, Yorba Linda

1Fit's clients have pretty remarkable things to say about their success: one man traded 100 extra pounds for a six-pack, and a bride-to-be had to have her dress taken in four times in a seven-week period. They've slimmed and strengthened their bodies through 1Fit's motivational workouts, which combine cardio, resistance, core work, and flexibility training. The high-energy classes are led by certified personal trainers, but the group format makes them more affordable than attending one-on-one sessions or bribing Charles Atlas to share his secrets. Despite working out with others, students can tailor each class to their own goals and ability level with the help of the dedicated trainers' modifications.
