There are a few things you could try, personally, i've done this before when I was a lot busier than i am now.
I took some inspiration from this article
And basically did this. I could only really commit to two sessions a week, so i programmed those pretty precisely. If I could make it into the gym 1-2 more times, i just did a straight forward assistance workout, 5x10 for some weak points. I still used a regular 3 week DE cycle, but it was obviously spread about quite a bit more. Something like this
Week 1 ME Workout, assistance days if I had time
Week 2 ME Workout, assistance days if I had time
Week 3 DE workout, assistance days if I had time
I'd also sometimes include depth pushups and box jumps in my warm up. I didn't get any slower while doing this, but Im back to the standard four day template now.
