Or at least consult a personal trainer. If you have trouble staying motivated, a personal trainer can be extremely beneficial. Having someone hold you accountable for your actions makes you more likely to do what you’ve said you were going to do. In addition to making sure you exercise regularly, a personal trainer can show you how to perform your workout for maximum advantage. Most gyms are staffed with people who will create the exercise regimen that’s best for you and help you through it. The goal is to ensure that you are exercising correctly and at the proper pace. If you can afford a personal trainer, he or she will encourage you to commit to your routine and to push yourself just a wee bit harder—all of which is good for your brain. If you’re not able to afford a trainer, then find a workout partner who can help serve the same purpose.
