To make your calves appear smaller, you can:

- Focus on stretching and elongating the calf muscle rather than bulking it up through Yoga and Pilates.
- Stretch your calf muscles to avoid shortening them.
- Do exercises such as touching your toes, downward dog, walk the dog, and seated, banded calf stretch.
- Lower your calorie intake and burn more calories through exercise if you have fat calves.
- Adjust your routine so that instead of bulking up, you lean out your muscle form in that area if you have muscular calves.
- Reduce the size of your calves by skipping direct calf work.
- Get on top of cardio to reduce fat and make you look skinnier.

You can also watch your diet in addition to exercising regularly. In this case, you have to figure out how many calories you need to eat to lose weight. Then, set a goal.

I hope this helps! Let me know if there's anything else I can help you with.
