Sure. Weight work is a must. Example-I was the fastest in my life just after my army. That was the best shape i have ever reached. Food, resting/sleep and hard training with surgical precision. Comparing to those days, now i am more like a grandma
Regarding your question about workout my advise would be-find the best way, your way, size and scope and type of training. Best quidelines you may find on interenet, of course.
I used I and I still use strength factor training (divide total weight with minutes and you will get factor: pounds/minute or ks/minute. for example if you can push and pull 6t in 60 minutes then your factor is 100 kg/min). High intensity, no more than 60 minutes.

I hope it helped
