I want to start doing some simple strength exercises. I don't want to bulk up at all (that might require new clothes ), just develop some tone/useful strength/flexibility. I was thinking of doing bicep curls, rows, tricep extensions, and sort of a combined clean-row-military press type of thing with relatively light weights (starting with 15s). Possibly some pushups and situps, that kind of thing. My main question is, since I don't plan to break muscle fiber down by doing these to failure, do I need to skip a day or two days or whatever in between, or can I just do it every day? I think I'll be more likely to stick with it if I can do it every day rather than trying to remember a schedule. Thanks.
