Jabz is so fun! Lots of stations keep you moving, so the time flies by. Also, heavy bag work makes you feel like a total badass. It's a little intimidating to walk into since there isn't a lobby or someone working the desk to greet you, but as soon as the trainer realized I was new she was super welcoming and incredibly helpful. She took me around to all the stations to make sure I was comfortable with the workout. I highly recommend it to anyone who wants a safe fun workout you can take at your own place.
A few things to note:
1) you have to have mma gloves to punch the bags. They sell them there for $35, but you can get them way cheaper at any sporting goods store (or target or Amazon)
2) they alternate between muscle groups, so you may not get exactly the workout you'd expect (but it's still great). Just be aware if you expected a total body workout you might get more upper body or core.
