I am so glad to have found a thick pair of cuffed sweats, it seems impossible these days. They work for exercise, but I honestly want to wear them all the time. I am 5' 4" and 155 lb. I got a large, and they are roomy but not overly baggy. They also don't have that weird crotch fit that a lot of sweatpants do. Love 'em, just getting my 2nd pair now.
