I should probably say additionally that while this advice, imo, applies to 90% of people, I have had personal friends that I’ve seen train 6-7 days a week and sometimes multiple times a day with incredibly resilient nervous systems.
One of my best friends in college played football for his first year (BIG D1 school) until concussions forced him to quit and moved onto the bbing scene after. I watched him train hard and heavy for 1.5-2 hours 7 days a week, sometimes twice a day, and it never seemed to impact strength/recovery and he never got injured. Easily the strongest dude in the student gym and since I knew he was broke as shit and he got all his gear from me, I knew what he was running and he never went over 500mg test a week with 300-400mg being the normal range.
Just to say that we don’t know you so you could be an insane outlier like this dude was but, generally speaking, that isn’t the case for most.
