When I worked out in the gym a long time ago, I did things differently.
Low weights, but lots of reps.

For example: with bench pressing I used 30 or 35 kg (70 ish pounds) but I did 3 times 30 reps.
I even did one bicep excercise with just the bar.
That got me some laughs until I challenged a muscle guy to follow my rythm doing 120 explosive reps. After that, everything was cool

I supplemented my martial arts training, and I didn't need or want bulk or raw power. I cared more for muscle speed and endurance.
