I'm a regular gym class goer, mix of cardio at circuits, strength and some spin classes too, probably a leisurely swim once a week. I am intrigued at how some girls / women achieve their glutes/rounded bum look! Often accompanied with a small waist and very toned upper thighs. I've come across shred / cut terms recently and naturally curious as to how people achieve these very honed and toned bodies! I'd say I do on average 3 exercise classes per week with no actual gym dedicated time. I imagine diet must be a big contributing factor, is it all about protein intake and a lot of hard work?
