With High intesity I mean high intensity in the working sets, you should be psyched for your heaviest working sets you should also do it all out 110% if u dont scream like a dying bull at the last reps on the working sets you are not doing it right, it should be ALL OUT MAXIMUM EFFORT FOR ALL REPS Imagine yourself that if you dont hit each rep you'r GF will die or something.

Ok, this is how I workout on bulk, I do only 1 failure set / excerise

for example back : Barbell rows, Sitting Rows closegrip, Latpulls, latpulls closegrip, DB rows.

6 sets to failure total.

I warmup slowly for examle if im gonna hit 120 in barb rows, I do (kg's)

20x20 30x15 40x10 50x8 60x6 70x5 80x4 90x3 100x2 110x1 120x9FAILURE

1 min rest on warmup sets, when the weight gets heavier around 80 i start resting 2min / sets between the 110 and 120 set i rest 4 minutes to get full recovery of ATP and get the lactic acid out of the muscle.

Then I hit sitting rows I start warmup heavier, since im warm same principle on resting,

for example 60x10 85x6 95x4 105x3 115x2 130x10FAILURE

and I go on like this thru all the routines.

Why so much warmupsets? I aim at hitting as many reps I can at as heavy weight I can handle, I feel that I need to warmup abit on every excerize to feel my joints and tendons are "ok" if I fele something fishy going on, I just go home and rest to prevent injury.

The sets at failure should be in the rep range of 4-12 IMO, you can also cycle this with hirep low rep periods and it works well for a change of pace, 2 weeks 3-6 reps 2 weeks 12-15 reps, you should strive to increase reps/weights each session.

This worked good for me last bulk strenght and size wise, but it can be abit hazardous if you dont know you'r body well you can risk injuries.

Squats and Deadlifts I never train to failure I stop 1 rep before failure and add another set instead.

One last thing If you feel like halfassing it just stay home n eat, and train the next day instead, if you cant go into the gym at 110% stay at home.

And I rest between working sets : Arms 2-4 min, legs n deads 5-6min, backrows 4-5min, chest db/bench presses 4-5 min.

this is to let the lactic acid out of the muscle and let the muscle restore ATP so you can keep up the intensity in the next excerize working set.
