Starting my second week of p90x 3!

Hi everyone!

I just recently discovered this subreddit so I figured I'd post. As the title says I'm starting my second week of p90x 3 doing the classic and loving it so far. I completed the original p90x about 3 years ago and got amazing results but as times have changed I just don't have the time for the hour and a half work out. I just had a few questions for you guys. Those that have completed x 3, are you happy by the results? Also I'm taking the p90x vitamins as well as their new pre workout powder. I've never really used pre workout and honestly so far I don't really feel like I have any more energy then usual but perhaps I'm not waiting long enough after taking? Any suggestions or experience with the vitamins and preworkout actually working please let me know.

Lastly I wanted to give my stats I'm 25 and about 5'8 Male. When I started I was ~ 196 pds. After a week of changing up my diet and I now however at 190.5 and 190.6 which I think is awesome. I did take pre p90 pictures so I'm hoping to record my change over the course of the program.

Any advice or words of encouragement you guys can give are welcome. I can't wait to go through this journey with everyone here!

Once again thank you for any and all replies I really appreciate it. Let's bring it everybody!
