While working out tonight, I walked/ran for 15 minutes on the treadmill and started to warm up with light weights (one set of overhead barbell press). I then noticed that my left arm was engorged with blood - like a “pump” as if I had been working out intensely for a while, but my right was not. The medical advice line thought it wasn't cardiac, but I'd like to figure out what the cause might be. [more inside]
Is it better (in terms of muscle building) to do a large number of stomach crunches quickly without pausing at the 'up' part of each crunch, or fewer but pausing and holding the muscles tensed for a few seconds with each crunch?
I have just ramped up my exercise a little, adding some intermittent jogging to my long walks (I'm every other day, or every third day). It has been several years since I did any sort of running more than an occasional dash to catch the bus, and my quadriceps are sore. Searching online, I have found advice that ranges from "do not do any more exercise until your muscles are no longer sore" to "power through no matter what!" MeFi, what should I do to mitigate muscle soreness and keep myself in good shape so I can keep exercising?

I'm interested in finding good, scientific, non-biased information on weight lifting. Almost everything I seem to find online and in print is either unsupported or linked somehow to supplement manufacturers. Where can I find real deal?
