You have a good base training regime. But take it from a fighter, you need to do more sit ups and push ups. I'm also concerned if you're learning proper technique. Look around the web and find videos or pictures of someone demonstrating the techniques and emulate them.

hey, I'm doing some martial arts, too, and yeah you definitely have to add some more sit ups (up to around 100) and push ups (as much as you can handle but around 50-100, you can go up gradually)
You didn't write it, so I don't know, but do you do some stretching exercise? That'd be good too.
And I only worry about one thing- you may strenghten your muscles, but what about some real fighting experience? Coz muay thai is a really..well..HARD and violent type of martial arts!

good luck ^^
and thanks for the fav on my art piece!

focus on technique, shadow sparing and working the bag will defiantly help, spend a whole day on technique and the other two train hard. this way your technique will stay strong and you'll be fit to, technique practice should not be an aerobic exercise.

If you can see it already there is no point in taking the picture.
