If you hard deads it will be very hard to do squats with only 1 day rest… I dont believe you can recover that fast - you will have to compromise on weight and development…
Yeah that’s the single biggest concern of mine with this program. I’m not sure what to do about it. The deadlift works your posterior chain so I feel it has to be on the “pull” day (day that works the rest of the posterior chain and antagonist muscles).
However, adding “push” leg work (squats, quads) into that same day would make it a 2 hour workout or something – too much for one day and out of balance with the rest of the program.
