Wearable fitness trackers are everywhere these days. Everyone has a GPSwatch, companies like Jawbone have turned to slightly stranger form factors, while AT&T and Under Armour are putting sensors inside clothing. Students at Northeastern University think the latter have the right idea, and have put an array of electrodes inside a compression shirt. The apparel is part of system being called Squid, which also includes a smartphone app and an exercise tracking site. Unlike other tech that ends with monitoring hear rate and tracking GPS coordinates Squid can actually gauge muscle activity and count reps so you don't have to. The shirt probably can't tell the difference between a bench press and push up, but at least its one less task to worry about while whipping yourself into fighting shape. No word on if or when the system might become available to the general public, so you'll have to make do with the video after the break to see it in action.
