That is understandable-having doubts.Julio.
Don’t let that put you off, trying out a few classes. As you’lll need at least a few to get into the ‘swing’ of things,at first before you’re inspired enough to home practice.
I would suggest-
**Iyengar yoga- regarding asana the teachers aree usually very well-trained,like
attention to alignment and placement of limbs ,so safer. plus poses may be held, least now and agin. and it’s medtitative. they may teach using props(bricks,blocks and straps) that provide support in some of the poses.
kundalini yoga may find a bit hard-core & advanced,say on a mental & spiritua level
hatha is asana and praanayam so covers most styles.
Iyengar is a good place to begin your introduction to yoga. as most folk find it easier to open up their mind via opening up their body and freeing up restrictions and tensioons there,holding them back as most people probably have such.
You could go with kundalini bu you might find it a bit " out there" or off-the-wall., (theory and practice.) as well as challenging.It’d probably be a bit much i supect for a absolute beginner though depend on their intensity level.
You could do them all in the order you suggest ,then revisit them all again But safety should be youur No. 1 priority and a good teacher can help in that regard.
So find the best teacher you can find in a style that is also safe- alignment based asana i.e iyengar style.&be wary of teachers that just rush from one pose to the next without much mindful pause or control, or clear purpose.
Mindful instruction and direction with a clear purpose using clever sequencing is often a sign of a well-trained teacher( although if you’ve never taken a class you have’nt nothing to compare ).& those trained in iyengar often their training is always on-going , longer and more technically rigorous. they tend to have,set their own standards etc. so there is less chance of doing yourself harm. but yoga is aalso a mental thing toorequiring focus and concentration too. also finding teacher you gel with can help too as they all offer their own style,approach and personality. i’d keep the style gentle and mindful just to eer on the side of caution.
