You can build muscle and lose weight all in the privacy of your home so you’re free to sweat in solitude or bring the house down with your favorite workout songs. Because, while there are times when the gym is the perfect respite from a long day at work (you can get in, sweat, get out, and feel completely renewed), there are others when the gym is one giant irritation. There are too many people clanking weights, or chatting when they should be clanking weights, and all you want to do is walk back through the door and head home. Well, guess what? You can do that—and still get a killer workout in. Here are 8 options that prove it.

1. Barrel Chest Bedroom Workout
2. Total-Body Burnout Workout
3. Light-Up-Your Legs Workout
4. Cardio Blast Workout
5. Ab-Obliterator Workout
