yeah the change is fun. but your not growing in the long
run with that kind of training. your fooling yourself.
and notice chaos didnt pay attention to if he made progress or not. but hey it was fun. PUMP PUMP IT UP.
i disagree with you.
First, we need to define what you mean with "Progress".
If you mean hypertrophy of muscles, then i have to say that hypertrophy is about intensity of training, not weight or volume. Constant breaking your limits will lead to muscle growth.
If you mean strength, then i will say that maybe you will not build strength as fast as with other heavy training, but you will gradually improve ("progress") for sure. I noticed that same thing that was mentioned before, you get stronger with giant sets, but slower.
If you say conditioning ,i say that giant sets is the best training in that aspect i have experienced as well, because it seems that it burns a lot of calories WHILE training your muscles.
