Hi everyone I have just completed wk 1 as of yesterday. Trying to get fit and tone up following the birth of my 2nd child 7 months ago and have been doing a lot of walking past few months. Anyhow fitness wise I managed wk 1 ok, slow but steady, but my knee joints and back of heels really hurt! Knees hurt while running yesterday, just below kneecap, they still don't feel great this morning and hurt if going up or down stairs. Heels felt sore and tight after running tho generally feel ok this morning. So do I go ahead with wk 2 tomorrow or am I risking full on injury? I'm not sure whether it's just a case of needing to strengthen the joints or if there's actually something wrong? I was exercising prior to pregnancy in gym including a bit of treadmill but have never been a runner. Any advice welcome thanks!
