I will probably get flamed for my helter skelter routine.
Really I train according to what I feel like doing. Other than the squats and deads which I make sure to do every (1x) every week, I try to hit everything else twice.
For example I might do shoulders on monday with some dumbell shoulder presses, and some lateral raises and reverse flies. Maybe on thursday I will hit them again with some military presses and reverse flies. It just depends on what I feel like I haven't trained and what I think could use the most work.
My legs days specifically are the only thing that stay constant because if they weren't, i probably wouldn't train them with as much enthusiasm.
SL deads(just added 2 weeks ago)
Tue or Wed:
Then I do some upper body stuff.
I have been making some great strength gains training this way, and I also feel more anxious to go and train because i am not bored with a set routine.
I do the same general excersizes week in and week out, just in different combinations.
While I could probably make more scheduled and quicker strength gains training with a set routine, why fix something that isn't broke?
