24(m) Inneed of exercise advice

So I decided to finally work out to better my health and gain some muscle that I've lacked my entire life. I'm currently 24 years old, 6'1 and about 190 pounds. I only have a curl bar with plenty weights, 2 sets of dumbells 15's and 20's and a bench that can do incline and decline. Can someone give some tips andadvice on how to get started with exercises and possibly a routine to set me on the right track please?

Thank you.
