THANK YOU! lol. I was wondering if anyone was going to mention this.
I'm of the opinion that direct arm work absolutely has value, and should be incorporated. It just doesn't have to be half a dozen different exercises. As long as you have at least ONE thing you can do, you're fine. Barbell curls, as part of a program that also incorporates rows and pull ups, are sufficient for bicep development for most people.
Also, it's nice to have a beginner in here who is receptive to advice. That's not always the case.
I'll finish by saying I'm a big fan of 5/3/1, given your limited equipment.
@stronkfak why in the world would you recommend AGAINST 20 rep squats???? PARTICULARLY for a beginner??? 20 rep squats are an amazing tool for beginners, because it allows the trainee to perform a ton of volume, increase conditioning, and groove the movement patter without working with excessive, overly demanding loads. This is a MUCH better idea to learn squats than strictly working in low rep ranges. The best thing I did early on in my squat training was a lot of sets of 10.
