40 Day Strength Program 3 Days per Week?

Can the 40 day strength program, developed by Dan John and Pavel, be done 3 days per week or would that be inadequate?

It would be a giant compromise that undermines one of the key principles of the program (high frequency). You’d be training almost half as often as intended, which is obviously quite an issue. If you can only train 3 days a week, this program isn’t an option.

That’s what I figured. I can do the 5 days as I’ll be training from home, and the workouts don’t take that long.

If you mean

-then no

If just going on the original concept…
“For the next forty workouts, pick five lifts. Do them every workout. Never miss a rep, in fact, never even get close to struggling. Go as light as you need to go and don’t go over ten reps for any of the movements in a workout. It is going to seem easy. When the weights feel light, simply add more weight.”

-then absolutely fine
