The best way to make the most of your workout is to ask a pro. Although personal trainers are expensive, they can be well worth the price. Trainers run $50-60 per session, and each session is normally an hour long.

If a trainer does not fit into your budget, then it's still important to ask questions, especially if you're an exercise novice or have special needs, such as injuries or health conditions.
