This app calculates your weights if you are using Jim Wendler's 5/3/1 program, which promises slow and steady gains that will eventually turn you into the strongest guy in the gym.

What’s New

Version 1.0.2

Increased font size
Display fixes for iPhone 4/4s
Warm up is now properly 5-5-3 rather than 5-5-5

Please rate and give feedback, I will never put in ads or popups asking you to rate the app. I developed this for my personal use, but if enough people are interested I will add more 5-3-1/BBB variations, or possibly the ability to build your own workout plan.

I have another update coming in the near future that:
Clarifies some confusion people have had with what the weights you are setting are (it's your one rep max)
Allows you to undo a set by clicking on it again.
Allows you to disable the second set of cardio (like squats on bench day)

Simple and effective 5/3/1 BBB

Been using this App for almost a year now and I can't say enough good things about it! For those who are looking to do Jim Wendler's Big But Boring (or Boring But Big) routine this App is the best one I've found. I've been through multiple 4 week cycles and I'm seeing consistent gains. Just put on your 1 Rep Max for Bench, Deadlift, Squat and OH Press and off you go! All the warm up sets, work sets, cardio sets and accessory/complementary lifts are already calculated for the entire 4 weeks. I'm a slow-and-steady-wins-the-race lifter and I'm more than satisfied with consistent, albeit small, gains without getting over trained (which I'm prone to do). Thanks for the App and if there are any other versions I would be interested!

Love it

I have never given an App review before until now. This App has changed/improved my life...I can't wait to get to the gym to do my workout and I can't wait to leave when I'm done cuz I'm usually spent. My strength has never been better and I haven't felt this good/strong since college days. I guess if I have to come up with a gripe it would be to list some accessory lifts but I have come up with my own routine after the BBB work out. Thanks for this App I love it.

Developer Response ,

Thanks for the review, it made my day! I'm working on a 'version 2' of this app, and if you'd like to give me feedback as I develop it, feel free to send me an email at chris@chrisdwyer.me.

5/3/1 simplified

Out of the all the 5/3/1 apps available, this is by far the most simple.
To the developer: it would be great if there were a section for notes so we could keep track of accessory exercises.
Other than that it is a great app.
