I found I was actually less tired when I started working out more. Make sure you’re eating enough - even if your aim is weight loss, you still need to fuel your body enough.
I did Unleash day 1 today. Hmm, I kind of hated it, but then I really hate lunges and lunge variations and there was a shitload of them. Then I made the mistake of looking it up on the CG Facebook page and it’s full of “legs like jelly” and people using fucking ridiculous weights. Please. I actually often find myself dropping to body weight on lunges which I know is a psychological issue because I can do them weighted, but I just find them so tedious and energy-sapping. Anyway I’ll give upper body a go and see how I like that. I’m not mad committed to Unleash and might switch to Intent or something else if I don’t get on with it.
