Before ambition gets in the way of your physiology please consider the following:

• The first two to three weeks of any new exercise program should be considered a preconditioning period during which you progress slowly.
• Even with use of a preconditioning period maximum-effort fitness tests may result in server muscle soreness the following day.
• Allow sufficient time for recovery, improvements will not occur if your second workout is preformed before the recovery phase is complete (48 hours for strength training and 18 to 24 hours for aerobic and other workouts).
• You will need a minimum of 6 to 8 weeks to improve your aerobic fitness and 4 to 6 weeks to see improvements in strength and muscle development.
