Thanks everyone for your kind words - I actually feel a lot better. I took some diclofenac and had a bit if a rest and it isn't twinging as much now. I won't be silly and will leave DVDs until the weekend I think, and will go back to 2 or 3k weights!
Welcome to all the new shredders!
Virgin shredders - you will be fine. I hadn't worked out for YEARS before January this year, just a few half-arsed trips to the gym (where I mostly went in the jacuzzi anyway) - I last ran a lot and worked out in 2006. So I was really, really unfit. So if I can do it anyone can I am sure.
As to is it worth it and does it change your body - I posted this earlier on the low carb thread I am on here. I was rifling through an old handbag and found some body measurements which I remember taking in November in a fit of depression as I had put so much weight on.
It doesn't have my weight on but my hips waist and bust (but assume my weight was around the 12.3 mark as it was in December).
Hips - was 41, now 37
Waist - was 31, now 26.5
Weight was 12.3 now 10.9
Also I have gone on the site linked to upthread, using all my old measurements (apart from the measurement for my neck, which I didn't take back in November so assume it is the same as now, 12 inches) and according to the measurements I used to be 30.5% body fat (which is acceptable) and now I am 19.5% body fat.
This is probably 50-50 diet and exercise, but I probably look a lot fitter now than when I just ran, or went to aerobics once a week. I think the reason they work so well is that they are so easy to fit in every day - there is no way on earth I would ever bother doing an hr long DVD, but 20 minutes fits easily into a busy day.
I love Jillian.
