I know that doing yoga is haram as it is part of Hinduism. But what about doing certain stretching that matches with some yoga stretching. I follow a stretching routine that has some yoga stretches like
downward facing dog - You kind of need to bend your body like a dog.
Dynamic Frog pose - Be in a frog position.
is doing those haram? Note that i am not doing yoga. Just a stretching routine to stretch my legs.
