I have used the Lifeline gym as an alternative to weight training and have been happy with the workout. I have tendinitis that occasionally flairs up in my elbow area when doing certain weight training exercises. I don't have this problem with the Lifeline. There are different levels of intensity to choose from. It can be used as an alternative or as a compliment to weight training.

It seems like they are discontinuing the traditional Lifeline but they are offering an alternative that seems to be a new and improved variation:
