I always feel like I'm too fast in the gym. I'm trying to build mass so I'm usually going heavy doing 6-8 reps and 3 sets. If I'm doing a back/bi day I might do 3 workouts for my back and 2 workouts for my bis. The lifting itself maybe takes 25 seconds then I rest for 1 min in between which means I'm typically done my 5 exercises in about 25-30 mins.
Anyone else blast through their routine in and out? Should I be doing more? I usually just do 1 focused workout per muscle group then go about my day.
