For beginners, your own body weight might be enough to get you started. However, it can be hard to challenge your body without any additional resistance, so to progress, you'll need some equipment. If you decide to strength train at home, you'll want to invest in some basics, such as resistance bands, weights, and an exercise ball. Try to have a range of weights: a light set (3 to 5 pounds for women, 5 to 8 pounds for men), a medium set (5 to 10 pounds for women, 10 to 15 pounds for men), and a heavy set (10 to 20 pounds for women, 15 to 30 pounds for men).
Arnold used single-joint movements to complement overhead presses and isolate each delt head individually. Here, too, he sought subtle differences that would, over time, build better overall size. For example, the cable lateral raise in front of the body has a slightly different feel than when the cable runs behind you. Knowing how to do a given movement pattern on different pieces of equipment is, according to Arnold, essential for a bodybuilder to take his physique to the next level.

Let me refer readers to some of my other articles that detail these areas.
