This is my second Activ5 (I got one last year). I purchased the first, and fell in love with it. I gifted that one to another family member and this new one is mine:).
I used to workout frequently when I was younger, but now with Teenagers and everything that comes with that, I don't have time for the Gym. I was introduced to the Activ5, and after trying one 5-minute workout, I realized how impactful this device could be. Why?
1) Each exercise is calibrated to your strength at that moment in time. So no matter who uses it, or how strong or tired you may be, it gives you the workout that you can handle at that moment. [That's awesome]
2) I can choose to do upper body workouts, lower body workouts, core workouts, and specific body part workouts (chest, shoulder, bicep, calf, hamstring...)
3) I can do workouts anytime, anywhere... I usually do a 5 minute break at the office. I take it with me when I'm traveling (fits nicely in my backpack), and do a seated workout on long flights, or more common, I workout in the comfort of my hotel room.
4) The companion application has tracked my strength progression since I first started using it, and I have increased my strength by 100% on most exercises. It's taken me over 6 months to get there, but it's real, and I feel the difference!
5) There are some game-like exercise themes, buried in the profile, that change the exercise curve (your goal is to adjust how hard you press the device during a 15-30 second exercise to follow the curve). I personally like the shark chasing fish theme and the spaceship themes best.
6) Recently, they added a connection between Apple's watch and Activ5. Now my workouts with Activ5 also add to my Watch exercise ring, and I can also track my calories and heart rate while doing the workouts.
Who doesn't have 5-10 minutes everyday or two to get back in shape?
I highly recommend it!
