Hi all. I'm not religious at all, but decided to do Lent this year. I decided to give something up and start something new (positive). I opted for chocolate to lose and sit ups each day to gain. I'm not unhealthy and am relatively fit (I do things like Total Warrior and am also part of a dance group). That said, I don't tend to do a lot of sit ups and not done them in ages. Mixed messages about whether I should or not. If not, I could do the squat challenge or plank challenge? Thoughts?
