I was the same way bro, took me years to figure out the nutrition and how to get lean. You have done well bro, you are looking much better.
It also took me several years to learn that training primarily with machines and cables was sub-optimal for getting results. Once i restructured the majority of my routine around compound Barbell / Dumb bell lifts and supplemented the rest of the routine with a few machine and cable exercises, i got much better results.
No one builds a solid foundation of strength and muscle using machines and cables. Body builders train this way, but if you ask them how they built their foundation, it wasn't from training that way. Superior genetics and lots of drugs will allow certain individuals to grow no matter what they do. I dont think either of us fall into those categories.
Train how you want, but just know your training sub optimally and leaving gains on the table. Sure the sarms will help you build some muscle regardless if your training is optimal or sub optimal.
