Several of us here at Mashable enjoy working out, mostly to combat “the blogger 15,” but we also realize it is easy to get bored with the same exercises. We’ve put together a list of 15 sites with exercise videos that are bound to liven up your routine.

There’s no need to invest in expensive DVDs you’ll watch only once when you have a wealth of instructional videos at your fingertips. Try these and let us know which ones work for you.

Back in November, we brought you news of a bill in Congress that would enlist America’s higher educational institutions as an enforcement arm of anti-Piracy groups like the MPAA and the RIAA:

In the House Education and Labor Committee’s comprehensive College Opportunity and Affordability Act, there is a small section dictating that any university in receipt of federal funding shall act as an enforcement agents for the stoppage of unlawful downloading. The committee unanimously approved the bill today.

According to Ars Technica yesterday, the Senate has passed the same bill with the peer to peer provisions intact. The gist of the provisions are that all American universities that wish to continue receiving public funds must “begin authoring formal piracy deterrence plans.”

Of course the MPAA loves this, and has already drafted and is readying for release self-described “campus briefing books” that will detail the anti-piracy provisions and what colleges must do to comply with the new regulations. Also included? Helpful hints on how to stop P2P traffic and detect copyright infringement.

This, of course, is an abortion of the process and is what looks like is a successful attempt to transform American educational institutions into law enforcement branches. At this point, though, there is little that stands in the way of this becoming law, since this “harmonizes” the House and Senate versions of the bill, and the executive branch has done very little to stand up for digital rights thus far.

Mashable is currently in Miami, where two lucky readers and event attendees will have a chance to win tickets to South by Southwest. Later this week, Mashable is headed to Boston and then New York City.

During each of these SummerMashes, attendees have a chance to score some sweet tickets to Austin’s hottest interactive festival: SXSWi 2009.

Yesterday, the SXSW Interactive website relaunched with all-new artwork and site architecture. Also, yesterday was the first day that you can purchase a registration for the 2009 event. Remember, the earlier you register for the event, the lower the price to attend. Registration early also gives you the most possible downtown lodging options. In other words, book your room now via the SXSW Housing Desk before your hotel of choice sells out (and trust me, they will!) The 2009 SXSW Interactive Festival begins Friday morning, March 13 and ends Tuesday evening, March 17.
