Any moms doing or have done the 30 day shred?

If so, I'd love to know how you do it? Do you do it while your children are asleep? Are you not afraid of waking them up? I live in a 1,000 sq foot apt, so I'm a little concerned about the noise? Can someone give me an idea as to just how noisy this would be if I did it at night??

Thanks,

A mom of three year old
