How long and how often you will need to work with a Personal Trainer can vary depending on your goals, your current fitness level, how knowledgeable you are, and more.
Most clients will see their Personal Trainer 1 to 2 times a week and work with them for a few months, but this is completely flexible.
For example, if your goal is to learn how to safely use weights, you may only need to see your Personal Trainer once a week for a few weeks. If you have a longer term goal such as weight loss or building muscle, you may want to work with your PT for a few months and see them twice each week.
