Go onto the intense muscle forum it’s all written on there and follow it exactly as Dante suggests…
2 way split (upper lower) done 3 days a week
Most sets are 11-15reps done via 3RP
Squats/leg press widow makers
One thing I did read is Dante suggests slightly higher rep range for older guys or just run with top set back off rather than all the widow makers and rest pause sets
But depends on the person, run it as is and see how you get on!
