I used to train heavy until I reach failure or close to it.
Since my gym had changed equipment, I'm afraid to do that because the new bench presses don't have safety pins anymore so I can't crawl out from underneath.
Now I train close to failure and then do drop sets at 80% of max for ten reps, then another 80% for 12 and another 80% for 14 reps. I could feel the burn I never did before with straight heavy sets of 5/3/1.
