2 min between compounds' (excluding DL) sets
1 min between isolations' sets
3 min between deadlift sets
good starting point for bulking (5-8 rep range) ?
bulking range is more like 6-12 than 5-8. your rest periods are fine though. you can take up to 90 seconds if needed on isos.
Since I've used DC type rest-pause I noticed better strength increases. I since then went on to experiment with 30, 45, 60, 90, and 120. I found that I respond better to shorter rest periods. I will be using 30 sec rest periods moving forward.
The big problem with short rest periods is that I could hardly do the second set with the same weights let alone do a third set. So I've been pyramiding down with shorter rest periods. I do take full rest after squats, deads, and 60 for rows and pullups.
I would love to hear more discussion on this topic as well.
