I'm not strength training right now, I need to get everything moving again for a while. I'm old now mate, it takes a while before you can lean on the joints and tendons lol.
Here's something to think about...
This literally adds fatigue for no extra muscle growth. Fatigue is bad. Take enough time between sets so you can use the muscle again effectively. How effective would a leg day be if you pre-exhausted your legs by running 25km? I get it, if that's what you want to do, then more power to you. If growing muscle is your thing, then running sets back to back with little rest is not the best approach. I've seen that trend in you for a number of years now and it's worth pointing out, as you can make better gains for less pain and fatigue.
Anyhow I'm off to the doctors to see what my blood looks like
