A less than optimal exercise routine is entirely possible. Do you have any tips? Bad technique or not enough variety is certainly a concern, especially when working out on your own. The trouble is, when I try to find alternatives, they usually seem to require a significant time and/or money investment which I can't do right now (e.g. getting a personal trainer, or adhering to strict regimes). If there any any simpler resources out there I'd be happy to hear about them.
