Lifting Heavy with rest or Lifting light with no rest.
I used to lift heavy all the time. Set of 8 then rest for 1 min or so. I would do max of 3 sets working each body part 5 times.
I have since started working out as 4x10 with no rest also working my sets as supersets. I have noticed that the strength is not there anymore but I am getting my defined and my muscles are getting larger. I will work the same body part 6 to 7 different exercises.
I would have thought with Tren I would have the strength thru the roof as I did the the past..
I do get gassed out on my new workout schedule thou.
