I so want to keep up with the couch to 5k- I think it is something I could really keep up with! I have practiced Pilates once a week for four years- it has been amazing for my strength, but really need to work on my cardio! I've enjoyed the first few weeks, but have done one session only of the second week, as a have a dull pain deep in my right hip socket. It started on the second session of the first week, and I thought my Pilates had sorted it, but it came back on the first session of the second week and remains almost constant. Am I going to have to give up!! Feeling demoralised. Can anyone give me advice please?
