When you come to train with me, it may be only twice or thrice per week for 45 minutes each session.
To make the most of your time, I encourage you to get into the proper mental state before you start. This means trying to clear your mind off the daily distractions and begin to focus on yourself. How are you feeling? Do you have any aches, pains, or joints that you should avoid training (and also tell me about)?
Next, turn off your phone. Use it only for emergency texts or calls. Give yourself 45 minutes of undivided attention.
Get to your class or training session a little before it starts. If you have any concerns or questions, ask. Do not miss the warm-up. This is important for many reasons, which you can read about on your own. You want to be prepared both mentally and physically for the training.
During the session, push yourself. Get uncomfortable. Good change comes from being uncomfortable.
Comfortable is sitting on the couch watching Netflix with a bowl of ice cream. Training is not the place for being "comfortable."
Life is short, and the time that you have to train is limited. Make the most of each session.
