I've done 5x5 2 years ago but didn't take strength training so seriously back then hence I went on a plateau and then i stopped going to the gym.

Well 4 weeks ago I went back to the gym this time with a more determined state. My starting weight was 57kg and now I weight 61kg my target is 75-80.

Now what I'm wondering is what program is next for me after 5x5? My brother's doing Wendler's 5-3-1 program for powerlifiting and strength. But as for me I'd like to enhance my strength and power endurance.

What would you guys recommand? My brother told me to try out either GVT or Westside for Skinny Bastards. What would you guys recommend?
