You will probably experience some soreness in the very beginning. This is normal. The trick is to differentiate between the phenomenon known as "delayed onset muscle soreness" (DOMS), and pain. If you are experiencing light soreness in the muscles (maybe they are tender to the touch), then you are OK to continue. However, if you are experiencing worsening PAIN in the joints or tendons (bad!), you may have overdone it, or you may need to get it looked at by a professional. In this case, we do not recommend you continue.
