I have to start this out with 1 simple thing, Yoga and the practice of yoga should never be a chore it should be something that you look forward to something that soothes you mind, body and spirit with the mere thought of beginning your practice if this isn’t the case then you have not found the style or nurturing environment that suits you.
Yoga can be for everyone and my suggestion to you would be to research the styles of yoga available and see which one suits your way of thinking. There are so many types out there just to name a few you have straight out Hatha the original beautiful style, Yin yoga which is deep, relaxing and restorative focusing on tendons and fasicia instead of muscle, vinyasa and quicker paced style and hot yoga (is as it sounds). For myself I both teach and practice Yin Yoga for the lovely slowness the medative relaxation of the style but within my classes I flow with Hatha base which give a touch of Yin but gives everyone that yang based muscle movement they love.
Once you have found the style you would like to try but are not sure as to how or if you want to try a class at a studio check it out on YouTube or buy, rent or borrow a DVD. If you do decide to go to a studio please please please never watch anyone but the teacher as they are doing their own thing and you really need to focus on yourself. Remember that everyone that is in that studio is doing their practice for their own reason and they may have been practising for years, been an athlete, gymnast, dancer or are just very flexible. Either way your practice is your own. For what it’s worth when I first started yoga some 25years ago I couldn’t even touch my toes and I certainly couldn’t do a backbend.
Be gentle with yourself and love the body you are in , surrender to the Beautiful, wonderful, gorgeous women you are.
Namaste for now
