I'd urge anyone starting out to build a base before worrying too much about isolation movements. I see these young guys coming into the gym & essentially all they do is isolation stuff (mainly curls). They could make much quicker & better gains with a different approach. Anything is better than nothing, but it's certainly not optimal. No beginner should have a program focused around isolation movements, IMO. Sure, throw in some curls every once in awhile, but your program should focus around compound movements.
Your initial linear progression will start to slow after a few months or so, but you can still make gains. I recommend a full year of a beginner-type program before looking into more advanced programming. Get your base, then you can do some isolation stuff if you want.
I ran what I'm doing (the big compound movements in all rep ranges) by Paul Carter, who is a guru in the field (& looks like he lifts unlike some "experts") & he said I literally couldn't be doing anything better as a beginner. I do have quite a bit of experience if you put all my time together, but I've never stuck with it for any length of time for one reason or another. I've always been interested in exercise science, though.
I just came to the realization I need to get busy. I'm very athletic & really never had to do anything to stay in good shape, but I'm 60. Even though I was in decent shape, especially for my age, I was starting to lose a little mass, felt more tired than usual, etc. Lifting consistently has made a huge change both physically & mentally.
I go every other day using an A/B format where you alternate 2 different workouts, but both days are essentially a push/pull/legs full-body workout (6 lifts total, 3 each workout). Anybody can do this & get great results if I can do it at 60. Consistency is the key. You're going to miss days, but just get back at it as soon as possible (ideally, the next day). You also don't have to workout every other day to get good results. There are all kinds of schedules & programs you can use.
I'd be glad to help if you have questions about what I do. I notice some other posters are experienced lifters, as well. Maybe we can keep this thread going.
