Ive been able to increase 5lbs each time. Its been 3 weeks and the only lift that ive been having trouble increasing is the standing military press, and now i feel the bench press increases are getting tough. As for the 5 - 10 -5 - 10 I've felt really good with the DL increases and some days I just felt great in the gym so I bumped it up 10 instead of 5 and kept going from there. The guys in here would probably not advise increasing this way but it just felt right for me so i did it.
I'm new to this type of routine so my strength gains have been great. If youve been lifting for a long time the increases will be more difficult so id say feel it out and see whats comfortable. I also started off low in order to work on my form.
