I’ve been able to maintain all of my gains just by using machines.
Absolutely. You can maintain everything you have gained. Question is whether by using machines, you can attain the best level of definition to your muscles, assuming you get down to very lean levels of body fat. I only find that free weights, particular dumbbell work for chest, allows me to get a lower squeeze to the pecs that brings out the pecs more, as compared to machines.
Then again, today, I see a lot of machines with great design and interesting range of motion that lends itself well to isolating muscles.
They should make a study on this.
