Bought a 15 visit package w/Groupon and am SO glad I took the plunge! I, of course, consulted my trusty Yelpers' advice before purchasing and JABZ delivered!
The studio is a good size (I didn't feel cramped) and LOVE the fact we use real "boxing equipment" and have a ring/dummy. I want my upper arms to look like Michelle Obama's by the time I'm done w/my 15 visits. NOTE: I"m doing these sessions AND going to my regular gym (Mountainside Fitness) too.
Len (owner) seems very informed and is motivating!
Only drawback would be lack of signage - took me 10 minutes of circling to find it. :)
