Great workout machine for a home gym!
Color: White Pink
I’m really happy with this 2-in-1 stair stepper and ab workout machine. It’s compact but gives you a surprisingly good workout. The stepper gets my legs and cardio going, while the ab function adds an extra challenge for the core. I especially like that I can switch between exercises without needing a lot of space or different equipment. The machine feels sturdy and is easy to use once you get familiar with it. It’s a great option for getting a full-body workout at home, especially when you don’t have time to go to the gym. Overall, a convenient and versatile piece of equipment. Definitely a good addition to my home workout routine!

DON’T
Color: White Pink
DON’T! I was so excited for this and instantly put it together to use. Watched a few videos and got started. Here is why it'll sadly be returned: 1-Extremely flimsy and unbalanced (yes all parts for stabilizing are on) 2-Core glider doesn't work properly. 3-The arm placements for the core glimmer are built for someone with arms 2x the size of a normal human (yes placing elbows on the foam) 4-Seems cheaply made and the screws barely hold in place and I had two other people tighten (men) 5-Came missing a few bolts (I could of replaced them but not worth it overall)

I love it
Color: White Pink
Sometimes I’m weary of purchasing things without too many reviews but I took a chance on this item!(had 5 when I bought it) I’m really glad I did. I use it everyday during my pregnancy and plan to use it postpartum. It is a good workout and nice to have mornings before work to get a little exercise in. The part to strengthen the core took me a few tries to figure out how to use but now I love it! I don’t usually write reviews but I want to encourage you to buy this! It’s great for the price and helps me stay fit.

Good machine for the money
Color: White Pink
This is a pretty good machine for the price. It is a tad unstable on the hardwood floor, however it was manageable. Good workout on the glutes. If you’re really tall, I wouldn’t recommend it. I’m 5’2 and it’s perfect.

Disappointed
Color: White Pink
Flimsy. The ab side is nice but if you’re 5’11 it’s really really awkward to use. The stepper is nice but you can’t adjust the tension so you’re getting a workout purely from heightening your own pace. Also really nerve wracking when the peddles wobble as you step….Disappointed because I thought the ab side was a bonus addition but it isn’t working out as I would like. I am also very certain this was returned previously and not new. Not all screws were packaged in the parts bag, they were already screwed into the machine….

Great 2-in-1 Machine for Home Workout
Color: White Pink
I love that it can be used as both a stair stepper and an ab workout. It’s like getting two machines in one! The stair stepper really gets me working those legs and glutes, and the ab workout is great for those abs while also giving me a little extra workout for those arms and glutes. The product is sturdy and smooth to use ! It was super easy to put together. Simply unfold it and tighten a few screws, and you’re good to go!

Great value for the money spent, ignore the negative reviews!
Color: White Pink
Great value for the money spent! Took me about an hour to complete assembly. Felt both workouts immediately. Got a better workout then on my row machine and I spent half the time.

Did not come assembled!
Color: Black Blue
Horrendous, the description says it the product is easy to install and only need to unfold and fix the leg screws?! Not my order it came in a giant box inside the box the actual product box was ripped in pieces. The product is not assembled in any manner and there are no instructions or parts inventory. I am trying to assemble but parts don’t fit it’s a mess. I can’t return it because it’s huge and the box would never fit in my car. Terrible.
