Stamina Outdoor Fitness Power Tower

After owning 2 indoor home pull up/dip stations, this one is the most sturdy and stable I have owned. I have it set up outside on my concrete back yard patio and it is stable enough for what I use it for that I don't need to bolt it down. I lined the bottom with rubber garage door weather seal. I weigh 165 lbs. and use it regularly for weighted pull ups and dips, hanging leg/knee raises, toe to bar, windshield wipers, and the lower bar for mountain climbers. However, if you plan on performing any exercises on it that require you to change your grips mid-air (i.e. doing a gymnastics high bar routine) then you should definitely bolt it down. EDIT: I also agree with PB’s review that if you tie a resistance band to it, you must anchor it to the ground. It will definitely tip over once you pull/push the band away. It has been exposed to Southern California Santa Ana winds with gusts of 50-60 mph and it hasn’t moved. As for the height, I'm 5'10" and it works fine for me. If you're over 6 feet, it might seem short if you do hanging leg/knee raises or pull ups (you would have to keep your knees bent). The only minor issues I had was that the shipping box came pretty beat up and some of the pieces came with a few scratches/chips. I’ve owned it for 9 months and after being exposed to hot summer weather and then a cold winter/rain, the scratched/exposed areas did start to rust. So I had to use rust remover, used left over touch up paint and clear coat for my car and it has been fine. Also, the black caps were the only pieces that didn't seem to fit "perfectly." They fit okay, but they kind of pop out a little occasionally. The diameter of the pull up bar (1.5 inch) is thicker than the typical ones you find in home gyms and parks, which makes it more challenging, but I consider that a good thing because it forces you to focus on using your grip and back muscles. Keep in mind, this product does not have bars for neutral grip pull ups. UPDATE: Stamina has a new outdoor "Power Tower Pro" that does include grips for neutral grip pull ups as well as an adjustable plyo box. If those additional features interest you, you may want to consider that model, but it does cost a couple of hundred dollars more than this model as of this writing. UPDATE 2: 12/25/20, since there are no neutral grip bars, I’ve been using these orange grips for the past 5 months and the tower has been sturdy enough to handle them. Use at your own risk though since the grips were not made specifically for this tower, but the diameter of the bar meets the requirements for appropriate use of the grips. I bought a particular brand that has been advertised on my social media feed. Amazon does have a generic brand version. If you get these, don’t leave them outside. Remove them after use. The fabric would likely fray from hot/cold/wet weather. The directions were clear and assembly was easy (all of the pieces/bolts fit well, I was able to hand tighten everything at first and then used the Allen key to tighten everything at the end). As the directions say, don't tighten anything until the last step. Overall, I'm very satisfied with the product. I no longer need to lug my pull/dip chain belt and weight vest to the park to do my workouts and I can keep it outside without taking up indoor space. Photo 1: Garage door sealer used underneath to prevent possible sliding (it hasn’t moved in the 9 months I’ve owned it) Photo 2: Ab slings can be used (not included) Photo 3: Update 12/25/20, I’ve been using this product for neutral grip pull ups. The tower and grips have been stable so far. I’ll keep you updated if anything changes. If you get these, don’t leave them outside. Remove them after use. The fabric would likely fray from hot/cold/wet weather. Photo 4: A frequent question asked is how high is the bar? I’m 5’10” and my feet can touch the floor if I dead hang, so I have to position my feet slightly behind or in front. In the photo, my feet are slightly angled back.
