@zorah654 Consistency and diet. I've gotten more results this year with 6-8 hours of sleep than most my life with 8.
I am also doing a job that burns an extra 700-1000 calories a day and don't make much of it up until the weekends.
But when you got the volume that works with you, the protein, and the right supplement, the results come with time.
Also, I take ZMA's, beetroot extract, eaa's, creatine, and 2/3 scoop of whey a day. Bought the cheapest I could find. But those are the only supplements that I have had results with. If I had to choose, I would just use creatine and ZMA's and get the rest from foods. Zinc is lost during activities, so it really helps when you are overdoing it. Creatine is just good. Beets help with bloodflow, so also a better workout and recovery. Whey and aminos to boost recovery and make sure I get more protein in.
Then figuring out how much to work out(based on your recovery) and what exercises for the results you want. I built up my shoulders quick with lateral raises, now it's ass and chest time to catch up. Last will be back, but I can do 8 pull ups and that was what's important to me.
