Congratulations on wanting to train as a boxer minus the sparring and fighting. It is the best get in shape training anyone could undertake..but it is hard and requires discipline. We ran in the early morning because it was a 'wake up' for your body'. Be prepared to spend a minimum of six hours a day in your training. Your three most important exercises are the distance running (6 to 8 miles each run), sit ups (from the floor with knees bent--no machines), and the push ups. Throw in the daily dozen routines (jumping jacks, skip rope, running steps, bends, heavy bag work, etc). Since you are not doing sparring....finish your day off with wind sprints. Exercises can vary, but they need to be challenging, progressively harder, and most important--suited to your goal. Now combine that with the diet of a boxer and you will see results. Don't ignore recovery time.
