Do I need to buy 2 (1 for each arm)?
You really only need one. And in some cases, it’s actually more beneficial to only use one and work each side of the body separately. It builds better balance and core strength. Oftentimes, if you are using two weights, your dominant side will subconciously take on more responsibility than your weaker side resulting in an unequal workout.
What’s the weight range? Are there different sizes available?
The weight range is 12-42 lbs which you can shift through in 6lbs increments. There is only one size available at this time.
Do I have to charge it?
The base which it sits on has a built in charger. The charge by itself can last up to 14 hours.
Do they have workouts for you to do?
They don’t have live workouts like Peloton does but they do have a bunch of very good pre-recorded one which are available here.
Is there an app?
Yep. The Jax Jox app is a tracking app which also hosts a variety of pre-recorded workout videos. Available by clicking here.
Does it connect to Apple Health/Fitbit?
