To all you runners... I can't run at the moment, which is one reason I took up boxing again
Had surgery on both lower legs, just got another MRI last monday. Running and jumping rope is out the question for now so I do a lot of biking and circuit training. I read a lot of fighters do that as an alternative to running. I've actually improved in some areas due to boxing (lost a lil upperbody strength but was able to hang clean 185x8 despite losing 10 lbs)
Endurance really isn't THAT big of an issue, I'm usually mentally tired by the time I get to gym.. which is why I asked about a preworkout. Last time I just completely crashed and didn't even feel like doing drills midway through. It was kinda frustrating
I actually just bought an elevation mask so hopefully my endurance will improve even more
