Hiring a good trainer has lots of advantages:
- you don't have to think about what you need to do
- they show you safe vs unsafe movements and keep you safe during training
- it's an appointment, so you're less likely to miss. My trainer doesn't normally charge for missed appointments (too nice IMO) but I pay by the month so I have to pay if I miss
- my trainer creates several circuits of 3-5 exercises and they are done 3-5 times each. The circuits are designed so that different muscles are used in each exercise, ie, "active resting", so an entire workout can fit in a half an hour for example.
If you have the funds, highly recommend hiring a trainer. Now I actually enjoy working out 4x a week for 45 minutes.
