hi im 16. male 5'7 and 159 pounds
i want to either box or mma, but want to get in good shape before i do, i have a barbell and a heavy bag, this is my workout

due to a slating on a previous question, please can you improve or make suggestions to this workout
(i cant do pull ups yet btw)
and i want to get fit and strong BEFORE i go to boxing classes
5x 4 minute rounds of heavy bag work with 1 minute rest in between the rounds
then
8 curls with a barbell
20 7lb weighted jabs
20 7lb weighted uppercuts
20 7 lb weighted hooks
10 standing tricep extensions
thats to be repeated 3 times, with 2 minute breaks
10 press ups
10 sit ups
thats to be repeated 3 times
this is to be done 4 times a week, the other days i have a 4 mile run
and every single day i cycle to my manual job, which is a mile each way
so what do you guys think?? thanks for reading my long *** post btw
