As overall health is such an important part of our mission at Benicia Fitness we have recently introduced our brand new program, Healthy for Life.  To start with, we measure your body composition and body fat percentage as well as your levels of fitness when it comes to cardio, strength, flexibility, core and balance.   Based on these results and your goals, we then design a workout plan and or nutrition plan to help you achieve these goals.  We also offer follow up measurements of your body composition and fitness levels. You can choose to do the entire program or any part of it.
