I'm not sure what exactly what you're asking. So I'll make a possibly unsolicited suggestion.
1) You *might* be overtraining, but I can't tell
2) Stop doing isolation workouts, work your body as a whole body. The only people who should do isolation are either recovering from an injury or bodybuilders. If you want to get strong work your body like a body and not little pieces at a time.
3) Try a schedule like this:
Monday=Lift
Tuesday=Active Recovery (jog, swim, hike)
Wednesday = HIIT
Thursday=Lift
Friday=Active Recovery
Saturday=HIIT
Sunday= Do something FUN, hike, bike ride, whatever.
You can also up the lifting or HIITs to three times a week if you are getting enough rest.
Lift Heavy, Eat Big, Rest Often.
