In order to import your results, you'll first need to export them from your old platform. Once done, you'll probably have been emailed a .csv file. Download that file, you'll need it in a minute.
Make sure your gym's programming has been imported into CHIP so that the workouts and results match-up.
To import, click
'More Options'
Under 'Data' > click 'Import results from another system'
Select your results file you downloaded. Boom.
