Ultimate 2 is currently the best home gym that you can find at Bowflex. Great number of workouts for every body part will help you build up all your muscles. If you want results and want them fast, Ultimate 2 can bring them to you.
Bowflex has a "6 week Fitness Results Guarantee", which means that you can return this home gym if you are not satisfied with the results. It's hard not to have any improvement with this kind of equipment, though - just spend 30 minutes a day with Ultimate 2 and you will see your muscles grow. You can try over 95 exercises, they really cover everything, and you can change the resistance up to 410lbs. Working out on this machine is really comfortable, you can adjust to any position that suits you because cables are flexible enough for it and Power Rods have a more linear resistance profile than any free weight machine.
You can use a training manual and instructional videos to see what kind of exercises you can do and which muscle groups they are for. Those can be helpful for beginners, but that doesn't mean that serious users can't benefit from this machine. One more thing to note is the guarantee: lifetime on Power Rods and 12 years on other parts of Ultimate 2 home gym.
