The Arena solved all my strength training issues. Everything you need to use the machine is included, the workouts are pre-built, moves are demonstrated on the app, and I can easily adjust the weight in real time. The machine is sturdy, portable, and can be used anywhere. I can just turn on the machine, choose a workout, and go. It pairs perfectly with my cardio solution, and I can feel myself getting stronger after just a few weeks! My wife was a skeptic at first, but now she loves it too. I’m extremely happy with my purchase.
