Cardio in the morning for 1hr 30 mins, then weights about 6 hours later..

That'd be OK, wouldn't it?

I'm ok with the intensity, I'm just wondering if I'd be doing more bad than good to my body leaving such a short rest period between the two. Would be having a small meal in between the two as well.

if u are a boxer u shouldnt be doing weights more than once or twice a week so it shouldnt be a problem finding a time when u can get proper rest. although i wouldnt recommend weights at all.

Nah, the weights will be a light workout.

Not a heavy workout at all.

High reps, low weights is what I'll be doing. So I'll try and target certain areas throughout the weak instead of spending 3 hours a day on all.

not true, depends

You should do light weights 3x a week.

So I can do Cardio in the morning, 5x a week. Then weights in the afternoon for 3 of those days?
