Hello, Ive gone from 235 to 170 pounds, then I gained 20 pounds currently I'm at 190. I don't want to go back to the 200s, I worked so hard to get out of them. The eating is what gets me, and in the gym what should I be doing the most? And I'm terribly exhausted after the gym should i do a muti vitamin or a powder supplement to knock that feeling. I could really use the help guys! Thanks! Happy health!
