Few aspects of weightlifting are as satisfying as the instant gratification I get from a massive arm pump. Today's gun show requires you to fail at a fairly high rep range. That means your goals is to hit those reps. Don't be a meathead and try to lift max weight. It's not your job to show the gym your 1RM biceps curl.
You'll do more reps in the final supersets than the first two, so be particularly smart about what weight you choose.
When you're done lifting, get some HIIT done!
