The whole decade?
Definitely don't want to let aging slow down my training too much. As much (deserved) hate as Jason Blaha gets, he had a great video about not letting getting older stop you from training hard. Yes, you can still lift heavy in your late 30s and early 40s and even your 50s; you just have to be more careful about form, warming up, recovery, and overuse injuries. In fact, it's probably safer to lift heavy when you're older because you're less likely to ego lift.
If Shannon Sharpe is still outchea benching 315 in his 50s then I will be too.
