The boxing gym near my place has been closed temporarily due to Covid. I am beginner and my trainer has advised me to only practice the jab and cross for now along with a lot of endurance and core exercises. Even I do not want to add any complicated combinations to my training. Can someone give me some advice on what kind of training routine I can follow at home? I usually start of with cardio. My cardio is 10 mins of skipping/jump rope, after that I do some cardio exercises on the stairs in my house. After that I do 5 minutes of shadow boxing then I do a bit of bag workout. On the heavy-bag, i start off by throwing a couple jabs, then I do a 1-2 , a little bit of 1-1-2 and some 1-2-1. I would like some advice on how I can perfect the jab and the cross and what kind of training routine I should follow as a beginner. Any other insight would be appreciated.
