8 Signs Your Trainer May Not Be Qualified for the Job

If a trainer goes through his clients in a number of months or even weeks, it’s a clue into how much he struggles to motivate them and bring in the results they’re after. So Duffy recommends that you simply ask a potential trainer about his longest-lasting clients. “An experienced trainer will say they have clients for 5, 10, 15 or 20 years,” he says. This is a great way to find out how long the guy’s been around—and it also shows how effective his training style is.
