Does anyone here use yoga as their main form of exercise?

I find that doing a little exercise – enough to break a sweat- everyday is really good for my physical and mental health. I currently do a few minutes of yoga, just to stretch, and then go on a ‘stepper’ for twenty minutes. Could I substitute the stepper for more yoga? Because I’m going away for the summer and I wont have my stepper with me.

If you do, please share how long you do it for, and like, if it’s salutes to the sun that is the main part, or any info would be great, thanks!
