Smart fitness gear is often limited by being static and non-portable. (And, well, eye-wateringly expensive.) Think Peloton‘s stationary bike for spin classes or wall-mounted strength training rig Tonal. Great if you’re at home and can afford to shell out thousands on a fancy home gym, but what if you want to take your workout with you wherever you go?

Meet Straffr, a German startup that’s exhibiting at the TechCrunch Disrupt Startup Alley this week. The company sells a smart fitness band that you can just pop in your backpack and take with you when you hit the road.
