Hello & Welcome! :) I really resonated with your intro, in that I was also the same - would start with great steam and then after having pain would throw in the towel. Well, no more! I got sick and tired and angry at myself knowing that I was not doing all that I was capable of...and I am motivated now by keeping a promise to myself.
Just started here a month ago, and set myself up with a plan (and a promise of daily exercise). I have completed nearly 35 days of straight exercise, taking two days a month off..I will tell you that the pain I used to experience is now gone! You can do it and you are worth it! :D
If you are looking for a buddy, I'd be glad to be here for you! Blessings! 2499 days ago
