We might have officially found our newest source of female and fitness inspiration. Model Iskra Lawrence, who shut down the thigh-gap debate and a body shamer on Instagram, continues to keep it real. Not only is she vocal about body positivity, but she also kills it in the gym. She posted an Instagram video of herself completely crushing box jumps while holding a 22-pound kettlebell. According to her caption, “3-5 sets of 10-15 reps” is how she likes to warm up.
