Fitness Is Cumulative-not continuos

Small sessions of activity will yeild results. Mini "one minute solutions" are less daunting than setting aside 1 hour or even 30 minutes to exercise for a new mother. If one minute is all you can spare then use it, you will get results. Try performing 1 minute of exercise 3-5x a day. This is very beneficial for mothers who suffer sleep deprivation and are breast feeding as you will not "overheat" within one minute and you will have made the first step to your recovery and fitness goals.
A continuous exercise session is next to impossible with young children in the house and may push new mothers to burnout. Accumulation of exercise is crucial for recovery and eventual fat loss training. Oh and when I say fat loss training this is no longer than 20 minutes including warmup and cool down.
