Back on track though, this is what I'd persoanlly would roughly do (i used to thai box too):
mon/wed/fri
dips 3x20
pullups 3x15 (mix of wide/close/chins as you fee like)
front squats or one-leg leg-presses 3x20
3x20 hanging leg raises, no swinging.
^^ I usually go from one to the other in circuits with no rest
45 mins of relatively easy pace incline treadmill walking
thurs - boxing
tue/sun
either high knees skipping (my favorite), sprinting on a good track, or a good quality elliptical with the arm thingys:
30 seconds full-out i want to vomit, 90 seconds slow pace (x6)
use less reps/sets obviously until you can build it up.
Then when you become leaner, I'd drop the 45min treadmill and do more weights instead. Personally I wouldn't bother with the weights, I would spend the time on padwork/etc instead.
