Training an older client (78) and overweight client (31)

Just want some advice and tips for training these clients. I’m just certified through NASM and work at crunch.

78 year old client is not overweight but is a little fat I have her doing stability ball squats, step ups db curls chest press machine, split squats in a box arm circles and pvc pipe for warm up. She wants to loose weight and gain more muscle. I also have her doing 10-20 minutes on treadmill after.

Overweight client same thing for warm up

Split squats on box , box squats , db curls, step ups with weights chest press machine and rope pulling machine. And treadmill

Any advice?
