A device for improving physical fitness includes an ax-like device which is swung in a chopping movement. The device includes a hollow handle which has an adjustable weighting system mounted therein. A bell and a spring mounted weight are mounted in the handle, and the weight impacts the bell when a desired chopping movement has been executed. The amount of force required to execute the desired chopping movement can be varied by varying the length of the spring.
