So you want to get ready for a climbing competition? Maybe you haven’t gone hiking for a while and want to get your body in the right condition. Lifting weight is not going to exactly prepare you for a long climb. You have to do some cardio and resistance training to get yourself prepared. That’s why climb trainers come handy. While they don’t completely prepare you for long, intense hikes by their own, they do give you the better chance to stand adversity while climbing.

The more your work on your fitness with climb trainers, the more prepared you will be for intense physical conditions during your hike. With that in mind, here are 3 powerful machines that give you an edge over other hikers:

FreeMotion X3 Treadmill Incline Trainer: more than just a treadmill, this climber gives you a very intense workout and gets you ready for intense outdoors activities. Burns 3 times that calories at full incline and inclines up to 30 percent.

Bowflex TC5000 Treadclimber: a stepping machine and treadmill all fit into one device. It helps you burn more calories and get your heart pumping fast. Play with it for a while, and you’ll be more than ready to take on any mountain trail.

StairMaster SM916 StepMill: if you can climb the stairs without running out of breath, you are more than ready than most folks for those intense outdoor activities. This machine does more than that. It’ll improve your cardio and gets you in a better shape for your hikes.

The three above climber machines are not cheap by any means, but they are more than just treadmills, ellipticals, or steppers. If you are looking to improve your cardio, look no further than the above machines.
