Toning

This is what I currently look like right now. I’m fine with my stomach and how it looks, the only thing that I’m insecure about are my legs:/ My family has super bad genetics with cellulite and I’m starting to see it on my legs. I’ve had stretch marks on my inner thighs since middle school. I guess what my question here is, what’s the best exercises for toning up your legs? (I despise cardio) My legs are already muscular it’s really just me needing to tone up
