You can surpass in almost every physical aspect the normal limitations to the point of 'supernatural'. Strength is near infinite, however like a normal human being you are required to actually exercise and push your muscles to the next level, lifting tons of weight to become stronger than before, but once that point is reached your body won't revert to it's previous format despite possible years of inactivity.
