Nothing wrong with taking a break to reset when you aren't feeling right. Some people try to grind through it but I always find it best to break and reset so good job. Congrats on that vascularity man. That is amazing. You are absolutely crushing this.
It was my first workout back so i was trying to just keep it as simple as possible for the first day backz typically id do Incline chest press machine or barbell.
I always loved this hobby and take it seriously, you are right i didnt relaize how brutal until i started running cycles because i am capable of doing so much more, and offen times it mentally upsets me when i fall short.
