I do empty stomach cardio sessions 5 days a week. Everytime something different.
Mondays: 5 minutes on machines, 10 minutes pure abs and obliques HIIT style on empty stomach
Wednesday: 13 minutes of pure insane Crossfit style, bodyweight movements on empty stomach
Thursdays: 5 minutes machines then pure lowerback,core training for 10 minutes on empty stomach
Fridays: Calves, a bit abs for 15 minutes on empty stomach
Saturday: Shadow boxing for 10 minutes on empty stomach

My question refers to 2 exercises I wanna really excel in. Both Strength wise, and proper form wise. Squats and Deadz.

Would it be wise, to change one of these workouts for a 15-20 minute empty stomach training first thing in the morning for Squats and Deadlifts? Going very light, and with many reps and focusing on the proper form as perfect as possible every week? perhaps 5 sets of squats and 5 sets of deads, and then leave the gym.

You guys believe this would be a good idea? or somewhere along these lines?

Aim: Become stronger and better at Squats and deadlifts. Please advice! Before I start something not worthwhile.
