wod-generator
This code generates CrossFit WODs (workout of the day) with recurrent neural networks (Andrej Karpathy's char-rnn model). The network is trained on 5k WOD samples collected from various crossfit boxes. Despite of small dataset, the results are both fun and satisfying.
Some collection of the good results can be seen from here.
Funny results
Of course, not all the results are great. Here are some funny ones:
Zero WOD
0 rounds for time 15 minutes
800 mt run
10 sumo deadlift high pull
9 front squat
1 muscle-up
Rest WOD
5 rounds for time
20 minutes rest
Nearly imposibble WOD
5 rounds for time 20 minutes
100 double under
50 wall-ball
In this WOD, there is no row but the network still wants burpees over the row
7 rounds for time
18 dumbbell squat clean
15 burpees over the row
250 mt run
Some imaginary exercises
brusseane push-up
t-up
touster
lean & jerk
publ-up
dumbell burpee over the bar
hanging ring in
louble under
ode-hand dip
roundstand walk
tempo kim back extension
muscle sprint
pistol squat snatch
over clean
elite push-up
inverted barbell
rest clean
pill-up
Data
All the WODs are collected from:
- crossfit.com
- findawod.com
- crossfitbalabanlevent.blogspot.com
After collecting, all of WODs are syntactically normalized by hand. That's why the dataset is that small, I wish to feed a lot more WODs but all the sources uses different format, some uses abbreviation some don't. To get best results, whole dataset should be in the same format.
The dataset can be found in data/wods.txt, or better they are in wod table in sqlite database located db.sqlite.
Feel free to use it.
