I took a yoga class with a ham instructor. I should have left as soon as it walked in, but I was there with my dad who really wanted to spend the time with me.   The fat, it turns out, was a substitute for the normal instructor. Now, these are gym yoga classes, so they generally aren't incredible, but they're still pretty good. I knew, though...I knew this was going to be terrible.   So the first 30 out of 60 minutes was spent going through incredibly easy floor stretches...aka your generic butterfly stretch, touch your toes, etc. But not even that good. I looked at the ham instructor when she said, "just fold forward and rest your hands next to your calves," and something dawned on me. The yoga instructor was so fat and inflexible that she couldn't fold down over her fupa and even reach halfway down her calves to her toes. Explains why it never once mentioned deepening a pose to reach further...it couldn't.   Continuing on in stupid easy stretches, we had to do cat cow pose for a good 8 minutes. The kicker was the ham didn't even know the name. She told us it was the Halloween kitty pose. Not once did she mention the standard name. Just Halloween kitty.   Onwards to upward dog and cobra poses. You can see the differences. In upward dog, she said a variation was to put your knees on the ground...so almost cobra and totally removing the arm work (it's a variation she took). In cobra, she said to not worry about getting an arch in the back and just look straight ahead. So her variation of dog. I'm guessing she couldn't arch her back, so she recommended we don't either.   If you aren't picking up on it, she never once encouraged deepening poses. She said nothing should feel tense or tiring, which explains a lot. Even in yoga you have to push yourself and frequently push into soreness.   Later, still laying down, she had us on our bellies and told us to put our arms in cactus. There's nothing called cactus. She literally had us lay flat on the ground with our arms bent 90 degrees like a cartoon saguaro cactus. That was it.   She got her left and right wrong a few times, and if someone got confused (she would say, for example, to lift the right leg on both sides of a pose rather than right one way and left the other) and question about lifting the left leg, she'd start laughing and say, "Um, no? It's the right leg...for balance?" And students would just stare at her for a few seconds. It made it confusing to new people because you literally could not hold balancing poses on the wrong legs without falling. Fatty could have hurt someone.   Finally, the last main irritant, fatty tried to introduce chakras, except she didn't call them that. I have a gut feeling she didn't even know what they were called. This is how that went, and I quote: "it can help if you imagine colors in your body. Red is your feet, your legs are orange, yellow is the...uh...yellow is the...torso, green is your chest...er heart..., blue is your throat, your third eye is violet, and your crown is white. It just makes you feel your body more." So this yoga instructor fucked up placement, the colors at the end, and didn't even know what the fuck chakras were. Don't teach what you don't know.   The class sucked. This -shudder- certified instructor knew jack shit about what she was teaching, couldn't hold a pose (she'd go in for half a second before releasing. She didn't take that time to walk around and help people. She just sat there.), didn't encourage people to push themselves further or even offer the options, was condescending when she confused people, and only used extremely easy and boring poses.   Fats are absolute shit at yoga. It was a total waste of an hour. Added tl;dr Fats continue to "educate" us on shit they don't even understand, know, or out effort into.
