Which is better? How often? For how long? So many questions...wouldn't it be nice to just KNOW what to do? You are in luck! The answer is: Both are BEST...TOGETHER - Perform bouts of cardio with strength sprinkled in. "When designed and executed correctly, this strategy can very effectively overload muscles, producing maximum results in minimum time". ~IDEA
You see, the important piece is that you begin. Don't over think it. If you can't make it to your FIT4MOM workouts, start with a walk and stop every few minutes for some push ups or squats, then get moving again. Try this 3-5 times per week and you WILL see the results!
