I coach a Pilates based class that uses a mega former very similar to the lagree machine. I love the sturdiness of this device and that I can do almost any of the moves on this. However, if you’re used to boutique fitness classes with a mega former, you may not like this because the wheels don’t roll as smoothly even on flat hardwood floors- feels like youre hitting speed bumps or feels like your wheel is running over rocks (if you’ve ever roller skated before). Only three stars for that reason but overall it moves well enough and the handlebars seem very sturdy. Just wish it rolled better.Well built with nice features. Lots of workout and intensity options. Nicely packaged as well. BUT the app wants your phone number and won’t let use the app without it. The kicker is that the platform does not roll in a straight line. This makes it impossible to do some of the exercises with multiple repetitions.Wonder Core has struck gold. Outstanding!Simply the best AB machine I’ve ever had the pleasure of using. Extremely challenging exercises are so inspiring, I can’t wait for my next training session.Performs exactly as advertised.I have been looking for a picee of equipment that could mirror the effectiveness of a Megaformer ab workout. This does it! Quailty machine, no setup, easy to use right out of the box. Now i can do all of the plank to pikes i want at home! Highly recommend!I have been using ab-rollers for over 10years. As these product wear and tear eventually, it is impossible to get the same product again. That forces me trying a new product all over again, I was frustrated with cheap quality products I tried recently. I am very impressed with this product, absolutely no complaints. It is worth for your money, I took insurance just to make myself at ease as this product might not last for over two years.You have to be very careful not to hurt your back. Good pec and shoulder work out when you are doing ab roller. Not sure how well it work my full/ lower abs.I use this with some dip bars to recreate the Lagree microformer. It’s a great substitute - the resistance is similar to the springs on a megaformer. Abs, legs, everything it’s great!
