Where can I do this?
Are the costs to get started high or low?
Would I be doing this in a group, in a couple, or on my own?
Are there physical requirements that might make it difficult for me to participate?
Intense physical movement
So what's it all about?
There are several different kinds of boxing. All will give you a tough workout, improving your agility, speed, and coordination.
If you want to learn to fight, it can be tricky to find classes geared towards that kind of training rather than a boxing-themed workout. This is particularly true if you're searching for women-only classes. But they are out there (see links below for Chicago options).
Initial costs are primarily the lessons or gym membership. It is also possible to set up a home gym and learn using youtube or other online tutorials. Note that if you are in Chicago the Park District offers very affordable classes.
