I currently do 100 jabs and hooks (both left and right) and crosses and one 3 minute random punches on heavy bag for 5 days a week ie Monday to Friday yet I was wondering should I do the 100 jabs,hooks and crosses on Monday, Wednesday and Friday and on Thursday and Tuesday do ten 3 minute rounds on heavy bag with random punches, so my question is do I continue my first workout or do the alternative I had suggested? BTW my main area to improve is cardio and strength
