Just finished 4 weeks of fives...x 3 sets.
I'm reluctant to SD, because I've been going up everyother day on the weights. I was astounded today that I could add more weight. In fact, from reading other posters comments I'm in a good place. I add load/weight almost everytime I workout. I don't have to load the same for days at a time, and then add load.
I know it's too good to be true, and I'm probably close to hitting the wall...just can't see it.
So, like others have mentioned, unless I hear otherwise I'm staying with the 5s until I'm not adding more load/weight. EVen then, I'm thinking I need to give it a couple workouts before I do SD. Somedays I'm just not as strong in some exercises. I think that is mostly from having to adjust my exercise routine, because the gym is so busy.
I generally don't try to stay with what should be next exercise. I do have a sequence I follow as close as possible. Workouts at a busy gym make it hard to follow a strict sequence of exercises.
One thing I do try to do is alternate between exercises that involve pushing or pulling, with not more than 2 pull or 2 push exercises together. I can't tell for sure if it's a big benefit, but it seems to help in my case.
My routine is rigorous, but it has really bumped my metabolism up.
I never take more than 1 minute of rest between sets, and never more than 3 minutes between exercises. I know... I probably won't be able to keep that up in the 15s, but I sure will give it my best.
