I have a good gym setup at home, but find it difficult to keep my workouts going when I travel. This is a great solution! It folds up small to fit in a backpack, provides a decent amount of resistance, is easy to use, and offers a good variety of workouts for isolating various muscle groups as well as for compound lifts. Even at home, there are some lifts on this machine that I’ve incorporated into my routine workouts.Construction is plastic, but feels sturdy. I saw some reviews with concerns and it does sometimes make a creaking sound but I’ve seen this actually comes from some pieces rubbing together and not actually any build quality issues. It folds up quite easily and adding/removing weight is quick.It’s a little expensive especially since it only goes up to 40lbs, but if you travel a lot or can get enough use out of it at home it feels worth it. The online videos are great for walking through individual workouts, but it would be great if they came out with an app for easier navigation and planning longer workouts that target specific muscle groups.
