First-beware the listings recommending IMX from local sites. This studio uses various email addresses to vote multiple times for them in the nomination process.
I made several attempts to join the IMX classes because I was impressed by their friendliness and the look of the studio and site. After agreeing to let me join a class, they forced me to pay for costly private sessions before I could attend a normal class. Each time I finished those sessions they told me to take more-I felt like I was scammed. I've taken classes for years, worked out with personal trainers for 20+ years and have never seen anything like it. Melissa (the trainer) "niceness" was entirely superficial and fake--only used for initial sign ups.
If you're expert at pilates by all means join, but for anyone that hasn't been taking serious pilates training for years, stay away.
