Just stretch out the program (one of the 2 you mentioned). Since they are more whole body/big movements than isolated body part work it will still work.
Basically roll through the strength workouts and add the energy systems work (but at a lower volume) at the end of the workouts.
For example with the "Athlete lean" program you would do the strength workouts (4 of them) over a little bit more than a week. For example:
Monday: lower body 1
Wednesday: upper body 1
Friday: upper body 2
Monday: lower body 2 (week 1)
Wednesday: lower body 1 (week 2)
Friday: upper body 1 (week 2)
So the program will take you 5 or 6 weeks to complete instead of 4
On each lifting day pick from the metabolic/energy system work prescribed and do 15-20 minutes worth at the end of the sessions.
