Adjustable Dumbbell Barbell 2 in 1, Neoprene Anti-Slip Handle, Easy Assembly and Save Space, Workout Strength Training Fitness Weight Home Gym（66lbs）

I've been using these for over a year now and they have served me very well. You just have to understand their limitations- the main one being that you don't want to drop them on the floor. The other is that the max weight is 52.5 lbs. So yes, if you're very strong and you like going to failure, you might be a little disappointed. However, if you're an average person like me and just want to get in a decent home workout, these could be perfect for you. The adjustment mechanism is easy to use and the weight increments make a lot of sense. They start out with 2.5-lb increases with the lower weights and jump up to 5-lb increases at the higher end. You can do anything you would do with normal dumbbells- bench presses, shoulder presses, curls, triceps extensions, rows, flys, lunges, etc. The plates do move around a little bit, which can be scary at first. However, I've never had one fall out on me and over time you will develop trust in the equipment. I do feel like they aren't perfectly evenly weighted, meaning that you'll want the two red bar things aligned when you're doing your exercises. Maybe that's all in my head. In my mind, those things are a small price to pay for space and money you save with these. Here's my setup- I have a squat rack and associated bar/plates for heavy, going-to-failure type of workouts and then I have these in the corner for high-rep stuff or for when I'm not going to fail and don't feel like swapping out plates all the time. Yes, I know that's a weird, lazy thing to avoid when I'm trying to work out, but that's how the human mind works sometimes. These really make my home gym a lot more versatile and they take up almost no space. The price may seem high at first, but you just have to think about how much it would cost to buy all the dumbbells you would want. Then you might buy something like a 12.5-lb dumbbell not knowing if you'll ever actually use that one or not. Also, think about how much a monthly gym membership costs, plus the associated transportation. Not to mention the time wasted going back and forth to the gym. If you get these plus a good quality bench (don't go cheap on the bench), you're going to be able to stay in shape if you're motivated to do so.
