If you are looking for a comfortable pair of crops for workouts, you might want to check out the Relaxed Fit crops that are currently in (US) Loot for $49. They are snug through the rear and looser in the leg. These are a good pant for people with "athletic" thighs. I think if you get your regular groove size you'll be ok. There are some complaints with pilling in the reviews but that is true of a lot of the Lululemon items these days. For $49 I can live with some pilling. I've owned a pair of an earlier version of Relaxed Fit Crops (sold them because of the color) and own two pairs of Extend crops and a pair of Extend pants which are very similar. The snug in the booty, looser in the thigh is one of my favorite Lululemon styles for the gym. The waistband is a little looser fitting than Groove crops so you won't get that Spanx effect but you won't get muffin top, either.
