I tried out the HIIT 100s routine from the "forum which will not be named" and saw some great fat loss in 6 weeks. I wouldn't call it great "gains" in strength, as I'm just working back to previous strength, but the workouts were killer to say the least.

Personal tips that I've learned along my still short journey:
Leave your ego at the door.
Prepare. Showing up dehydrated, hungry, and tired will guarantee failure.
Be ready to fight for that grinder of a PR.
Listen and learn. Absorb everything you can, and assimilate that knowledge.
