Lost the weight but it’s all back and it needs to go!

Hi,
Years ago mfp and the support of friends here helped me to lose 4 dress sizes - but life happens and I’m back where I was and unhappy. Now I have damaged knees so can’t do the squats, lunges and jumping jacks which made the 30 day shred so great to use up those calories. Would love some new friends, to be accountable and share motivation.
