Does exercise raise you metabolism?

i've been trying to lose a few pounds so about a month ago i began working out vigorously everyday seven days a week and eating healthier and withing the first 2 weeks i had lost 10 pounds which was awesome. but my schedule got so hectic the last two weeks that i stopped working out. i started worrying a freaking out that i would gain alot more weight than i had lost because i was too busy to work out. but then on monday i weighed myself and saw that i hadn't gained a thing. so i googled it and found an article that said that working out does help raise your metabolism. is that true.
