My niece sent me this "Sexy Leg Workout" to try, so I tried it. It was filled with squats, leg lifts, and calf raises.
There are only 40 calf raises, and I tell you I could feel a burn from my ankles to my ass!! LOL I had no idea they were so effective. Yes I felt them in my calves too, of course, but also up and down the entire length of my legs and into my glutes. Either I'm doing them really really wrong (how bad can you screw up a calf raise?!)
..or I'm doing them perfectly and getting the right results. Maybe it's the squats adding to the burn too.
I've done the workout a few times now and it still feels the same, perhaps a bit less intense.
It's a nice change up though
