Popping in from the 100 pound club with my two cents
I have a pretty nice treadmill, we enjoy it very much..(although not NEARLY often enough on my part!)
I'm only 5' tall and have tried an elliptical before...I found the stride on it MUCH too large for my little legs! It was really uncomfortable for me..but if you're taller than that, all bets are off.
I do love the versatility of the treadmill, though..with speeds up to 10 miles an hour and an incline up to 10%..it's more than challenging enough for even my BEEFCAKE of a husband. Much more challenging potential than I'll ever need, which is nice.
There you have it

Have a great night everyone, and Denise..good luck, I'm sure you'll make an excellent choice for yourself
xoxo
