I do hot yoga and pilates in a studio (ie not a pod).
everyone has a towel on their mat because of the sweat. i dont want to imagine the pool of sweat around each mat if you have no towel!!! Maybe a hotpod is warm and not “hot” as in 38•C and 45% humidity??
Anyway, towels are either microfiber (go on amazon and type hot yoga towel) or an ordinary bath towel. Having tried both for many months now, here are my thoughts:
Bath towel
. sweat absorbent
.heat absorbent (wont make you sweat extra)
. Too short for the mat (and in plank, my feet are outside the towel and slip or i need to readjust my towel and its a faff)
Microfiber hot yoga towel
. sweat absorbent
. Looks the part
. Covers the mat fully
. Make you sweat more (probably because not natural fibers).
They both have similar grip (i have two microfiber towels).
I am using a beach towel nowadays as it tends to be longer and more rectangular than a bath towel. I really dont like how the microfiber makes me sweat extra though i still use the two i have sometimes.
in terms of weak hip flexors, yoga is not going to help much but have a look on instagram and you’ll see lots of videos about dancers working their hip flexors. Best exercises are seated leg lifts (check on IG how to do them properly), straddle leg lifs, rotations and extensions. Blocked knees extensions, 90-90 good morning, pancake good morning, lateral leg raise and rotations…. IG can be a useful guide and ankle weights will speed up your progress.
Enjoy!!
