We’ve all been there: You wake up 10 minutes too late to make it to your morning spin class (we're going to go out on a limb here and guess we're not the only ones to have ever paid for a SoulCycle class we didn't attend). And yet, you're pretty sure you won’t be able to live with yourself if you roll over and hit snooze. Yawn. Wouldn’t it be heaven if you just get your cardio and toning in from the safety of your apartment, instead?That’s where the workout DVD comes in. Yes, you read that correctly, but hear us out. We know there's something inherently off-putting about sweating it out in front of the TV — the lame music, the super-cheesy instructors, the nagging worry that all that jumping around will seriously piss off your downstairs neighbors. We get it.
