How can i keep fit?

Exercise eat well: a regimen of so many workouts per week with healthy eating habits will help you stay fit

Follow the following: Exercise most days of the week (aerobic work), eat fruits and vegetables liberally, limit saturated fats, increase fish and fish oil intake, have fiber with each meal, keep your weight in check, don't smoke at all or drink excessively (one or two drinks weekly). The lower the better on LDL and the higher the better on HDL.
