Yeah, I had a huge improvement in my posture from a lifting regimen, it really counteracts the bad habits from sitting all day. Deadlifts and front squats feel like they're the most effective. The great thing about lifting is that it trains your muscles to want to hold correct posture (as in, you don't need to constantly remember to sit up straight). Wish I had gotten introduced to lifting earlier in life, it always seemed like some intimidating thing that was just for the bros club.
