I go to the gym with an idea as to what I am going to do for a certain bodypart.
Sometimes I stick with that plan.....on other occasions I abort that plan.....just depends on how the first set goes.....If I have a change of heart at the last minute....I will switch to a different exercise.
I never really worry about reps or sets.....rather concentrate on feeling the exercise.....I get distracted if I put too much focus on counting reps and sets.....If I have a great pump....then I have achieved my goal.
^THIS^
I map out what I`m going to do for the particular bodypart I`m gonna` train,but it`s subject to change.......I train by how I feel.
I still do the same bodyparts each week on the same days, and do approximately the same number of sets for each bodypart..........only the exrercises change for the most part,or the order of the exercises.......I rotate them in and out weekly.
At times,if I`m feeling weaker or tired,I`ll train with moderate weight but take shorter rest periods between sets,this makes lighter poundages feel heavier than they actually are.......other times I`ll go heavier if I`m feeling good on that day.
I also like to incorporate lots of different intensity techniques at times..ie., drop-sets,rest pause,pre-exhaust super-sets,half reps and 1 +1/2 reps................usua
lly though,I stick to straight sets.
Gotta` keep it interesting or I just get stale/bored sticking to a rigid routine.
I`m all about developing muscle and being lean, as opposed to always just increasing poundages,but I train as heavy as I can for the reps I`m shooting for,and I push hard all the time.
As far as keeping track of weights from the previous workout,I never have any problem remembering what I did on the previous week.
Whatever you do in the gym,just be intense.
