Day 3 of insanity, holy shet. My body still aches / is sore but it's that good workout feeling so I don't really mind walking around looking like an old person & struggling when I sit and get back up, lol. It's mainly my calves & lower back. I could already feel my core getting stronger. Gotta stay motivated & focused so I can get some real ass results when it's over. Lehgooooo
