So, I'm trying to figure out a new lifting plan, since I guess I've been doing too much all at once, but I'm just feeling kinda confused. I'm looking at the the full-body workouts in the OP, but is that all I should be doing? I feel like I could do all that for each day in like 45 minutes. How long should rests be between sets? I think I'm gonna keep using the Smith machines for some stuff, but try to work in some dumbbell exercises, too. I know I ought to incorporate deadlifting or something similar in some fashion, but I know what to do about it. Or something like power cleans, I literally can't think of an alternative that can be done at the Planet Fitness I go to. I'm just kinda confused on what to actually do. Maybe my vocabulary of exercises just isn't big enough.
When you first start 5x5 you can get the workout done in like 30 minutes or less. It'll be relatively easy for a while provided you start light enough (you should be). In due time, it'll eventually take you significantly longer to complete each workout. I'd advise against the smith machine. The strength programs in the OP are as simple as it gets in terms of progress and programming. Simple works.
