Hi Dave. I'm still exercising and still doing squats and sit-ups but not hundreds or a thousand in a day. For a while after I achieved the 1,000, I'd do 40, 50 or 60 squats in a set from time to time but mostly I've been doing sets of 15 to 20 but holding weights (usually dumbells but occassionally a barbell over my shoulders). I've gradually increased the weights I hold but I'm still in "moderate" territory with them but, as before, I'll keep increasing the weight bit by bit (probably until the end of the year) so that I feel I'll have achieved some decent improvement. As for sit-ups, I can easily pop off a set of 100 if I feel like it but I usually restrict myself to a maximum of 50 in a set but do 4 or 5 sets.
Thanks for the interest.
