Do you have an iPhone/iPad? The Yoga Studio App is well worth £1.99.
If you mean the app by Modern Lotus (it’s £2.99 at the moment!) then I couldn’t agree more – really well done and would be worth 10x the price IMO. I use it most days.
No, idea if I would be able to do it effectively if I had just gone straight online.
This. Although you’ll probably benefit just by contorting your body to roughly match something you see on screen, there’d be a lot of little things you’ll miss. (And worse-case-scenario make you more susceptible to injury, I suppose).
I do a yoga class most weeks and the instructor is forever correcting little things like alignment (making sure ankles/knees/hips/shoulders all line up, etc) foot position, reminding us to concentrate on breathing, etc!
