Adrenaline rush -- good or bad thing?
Today, I cut down my rest between sets to about 10 seconds, and gave myself about 30 seconds between exercises. The idea was to hit the gym harder. During my last couple exercises, I got an adrenaline rush. I felt like I could have done all my exercises all over again with more reps than before. However, I was afraid of hurting myself and quickly left the gym before doing something stupid.
Is it safe to workout under the influence of adrenaline? I can see the benefits of using an adrenaline rush to my advantage (doing more reps and hence building strength faster). Then again, is it a danger to push my muscles beyond what they're normally capable of? (will I endanger myself of a "blowout"?)
