Few questions about Excercise

Thanks for your reply.

I always stretch before and after the work out. This time I din't stretch after the excercise because something important came up and I had to finish the work out quickly.
I didn't feel anything during the work out, it was after few hours that the pain started.

I don't do heavy weight lifting. About the improper techniques, well I've been following this dvd for few years.

I think it has to do with not doing the cool down and stretching after the work out.

Oh and those weren't bruises.....those were my vains. lol

Yeah...that's what it looks like.
