I’m a newly certified trainer, at age 50, and I have a friend who I’m helping get started on a fitness program. I was thinking of starting her out on the machines, like I was 12 years ago. Mostly to get her comfortable with them so she can use them when I’m not around and also to just get her familiar with how all the muscles work individually. Would you say that’s the correct way to approach it? I’m only asking cause I don’t use machines anymore except for the back sometimes. I like more of the body weight functional exercises.
