I woke up to my first hooping bruise this morning, right over the bony tip of my left hip bone. But I really think it is related to hooping wearing a pair of jeans, rather than softer pants. I could feel the waistband and the beltloops as the heavy wavy hoop was passing over them if it dropped low enough. I think I'll just tough it out and toughen up, though, because the best part of this is that I can just pick it up anytime. No getting changed, no special shoes... Yesterday, I hooped 10 min waiting for the oven to heat up, then another 10 min waiting for the fish too cook, then the third 10 min after checking on the fish. Half an hour of ab exercise completed, while making dinner!! (It helped that I was home alone, a rare occurance for me)
