Great for beginners like me

I’ve been wanting to get into weight training but had no clue. I heard of starting strength and 5x5 but was intimidated. Got this app when it was on sale and the first two workouts have been great and built up my confidence. It started me on 3x5 which isn’t too hard, but I do feel great after lifting!

Easy to use!

If you’re familiar with the C25K apps this will look super familiar. Makes weight training look so easy and is a fantastic and simple way to track your progress whether you’re experienced or a new weight lifter!

Awesome app!

I love this app. It is a very straightforward program. The auto timer for rest in between sets is a great feature! I also like that it takes your progress on a calendar. This was the best $5 I've ever spent on a app! Keep up the good work, Zen Labs!
