I can imagine this exercise is quite tiring, but it's a good sign when the legs hurt a bit after the training, since it's shows it has some effect. Without some exhaustion the training isn't really effective after all. A great way to stay fit nevertheless.

I like how you designed the pose, it's very dynamic. Certainly not easy to implement movement in a picture. Body design and expression are very well done too, good job with this artwork!

Yup, and I try to pick a more easy exercise to have a break from each hard exercise. But I just begun, so hopefully I will get rhythym to do more tiring exercises with easy.

Thanks. But now I want put even more energy in my future pics.

It's good to combine more complex with simpler exercises. Fitness needs to be fun too and overexhaustion can be bad for having fun. I hope you can keep up your rhythm, it's worth it.

That's good, always try to do what you can, but also try to have fun with it. Then you will be able to improve and keep your work up over time.
