Nice but – 300 Kettlebell Challenge: The GB Workout Challenge Series Review

Nice app great workout. It'll work you out . When my iPhone goes to sleep. The timer stops. I have to turn my phone back on and it eats up time there. So the time I have posted or tweeted is incorrect. Workout. Not for beginners. No mention of how to work up to this. It's just a do this. I could because I've experience with KB. But the challenge is great. Fix the timer so my phone can sleep
