Private lessons aren't something you sign up for on the fly. While they are effective, they can be an investment — thousands of dollars spent in the pursuit of a healthier lifestyle.
Many gyms or studios, however, have an option where you can sign up for personal classes with one or two other people. Whether you're jonesing to take a few sessions with a personal trainer or want private Pilates lessons, gather a few friends to split the cost. You'll still get the personal attention, but without the price tag.
Have you ever taken a "private" class with friends?
