Just my layman opinions here but I think a lot would depend on your current level of fitness, strength levels, velocity, flexability ect.
How heavy are you lifting? What lifts?
What are your goals for lifting, velo and body weight?
In totally generic terms there needs to time for recovery for the total body and the arm.
Good nutrition, good sleep, proper hydration are important. Doing daily arm care is important as well.
Looking at movement and flexability is a good way to start as well. Check out the How to Become A Supple Leopard for great info on mobility and movement prep. The book is expensive. If you can’t afford that the author had a bunch of free stuff online.
