Questions
Do I need to install anything?
No. It runs in the browser and you can add it to your home screen, where it behaves like an app — full screen, works offline for downloaded workouts.
What if I only have one kettlebell?
That is the assumption. Every program is built around a single bell; the three levels are what change the load, not the weight.
What happens after the three days?
$9 a month, charged to your card. Most of it goes to your trainer. Nothing is charged during the trial and no card is asked for up front.
Can I switch trainers?
Yes. A subscription is tied to one trainer; you can cancel and subscribe to another at any time, and your history and streak stay with you.
Is there a minimum time per day?
Five minutes. The dial goes from 5 to 60 in one-minute steps and the program adapts the number of exercises to whatever you set.
