HAHAHAHAHAH i AM a minority good one . i deny people human rights on the daily <| sep |> My phone has gotten slow and even laggy in apps and internet is stable . It actually seems like the OS is struggling to keep up with any kind of multitasking . <| sep |> As a beginner you CANNOT go over 4 . 672 hours per week of steady state cardio if you also do any amount of other fintess stuff . That is scientfically proven ! So . yeah . NO ONE on this planet will know how much you can workout . You can find out by doing too much and realizing it was too much . Other than that there is no way to determine how much physical activity your body can take . So just try it out . I don ' t think 1 hour runs are as important to boxing as most people claim . The last time I ran that long was probably a year ago , still my cardio has improved massively from doing mostly rope skipping for 1530 minutes every other day . Edit OK , pretty much every single day . It ' s not like going anaerobic will not improve aerobic conditioning . Those two are linked . For refuel I love porridge mixed with some honey and some berries ! Easy to digest , tons of energy and tasty as well . If you do multiple training sessions the best thing you can do is obviously have some food and sleep between , if that isn ' t an option I would advise to go easy in the first training session and harder in the second .
