Hello! I've been exercising for a year now - three to four times a week, about 40 minutes or so, mainly HIIT and circuits.
I love it but I do find that I am often a bit ache-y and often a bit stiff. I have been gradually upping the weights so I hope that I am continuing to improve. But is it normal if you are a regular exerciser to always ache, at least a little bit? If you don't ache, does that mean that you have plateaued? Or do I feel it because I'm a bit old (46)?
Not sure if this is remotely relevant but I am quite slim (some might say a bit thin) and don't eat much meat. Do I need protein/supplements? Thanks in advance!
