Working out on your own is great. But sometimes, you are better off working out with a training partner. The Lebert Fitness Buddy System can help. It is a fitness system that lets you work your core. It is made of ballistic nylon strapping with UV protection and works well in boot camps. The system provides you with stability and bi-lateral training and works many of your muscles.
You can use this to workout with a buddy or as a couple. It can also encourage team members to work better together.
