User reviews

Stable and varied

Great large selection of exercises, excellent UI/UX with minimal friction to your workout, and super stable app. Been using it for around 11 months now on an older phone and it hasn’t crashed once.
One critique is that sometimes the selected exercises will sometimes target the exact same muscle group in the same orientation direction etc the excellent exercise swapping tool fixes that though.
I was worried about getting an app from an influencer, but just like the videos Jeremy and his team put out, this product has been given a lot of thought and care.

Good but needs some practical adjustments

Like the first workout it programmed for me, good balance between traditional strength training with some stability movements mixed in. However there is no cool down after the workout is over, which is fine I guess because I can do my own thing, but with that missing the workout is not true end to end. The other issue I have is that you cannot listen to
Music at the same time as getting instructions. The log book also needs work because you cannot just copy and paste or doesn’t autofill you next set which is a little annoying because most often we repeat the same weight and same reps. I had the Ladder journal app and it has all those features I found to be missing here plus it has a lot lore options for different coaches and programs. Ie if you want to mix in yoga and or Pilates with strength training. And ladder is actually less expensive. I’ll keep trying it for the next 14 days but it’s not likely that I will subscribe.
