Whether for recreation, competition, work, or general health, we all need a certain level and type of fitness. The needs vary from person to person. Many gyms, and the personal trainers you’ll find at them, have a pre-defined “package” that they sell to all clients, whether suitable for that client or not. Suitability is a matter not only of what you need, but of what you want, what you will enjoy, and what you will actually participate as a lifestyle.
