No assembly needed just slide the foot rods in, adjust to height and jump in! This thing works and feels great! It’s very sturdy. Compact for storage. The wheels are super convenient if u need to shift in small spaces. Overall it’s perfect other than the pink lol I only wish this came in black. Luckily it'll be in my closet but still.Im just thankful to find a solid machine at a good price. The other types more commonly available look flimsy. This one holds your legs firmly and you dont have to hold anything to keep it there which is a huge bonus. It reminds me of the type they have at some gyms.So glad I found it!Time to get my middle split back! :DUpdate: I have to use my finger to unlatch the gear stop to get the lever back down for storage which is a small design flaw. Im used to it tho I just deal with it. Its WORKING my split is nearly back to where it was in such a short time! Ive been using it daily for about 3 weeks now. I take a moment to also lean back in the stretch for the hips as well. You have to keep your legs firm or it can add pressure to the knees so be careful about that. Im continually shifting around to stretch every muscle area. Excited to get back to a full side split!
