Your sure getting lots of options! LOL. Heres my 2cents
In the gym 3 days. Just work the basics, you know what they are. That will save time.
Pick 2 exercises per body part. You will be out in 30 minutes
Monday: Chest, Shoulders, Triceps
Wednesday : Legs
Friday : Back, Biceps
Umm?? looks a lot like my off season powerlifting routine.
Or you could do Tuesday, Thursday, Saturday what ever fits better
The other days cardio with your child
P.S. Your military, Thank you !!!!!!
