Group Training
Group training follows the same explanation as one on one training sessions only group training consist of a trainer and more than one client, it could be 2 or 10. The advantage to these sessions are that you will save some money on the session cost, the more clients at a time the lower the cost per session.
However, these sessions are only for clients with the same goal and experience or fitness level. If each person is not at the same level or working on the same goal all involved will not receive the results that they would when training one on one.
