The spike depending on the volume in fitness spider chart should be category dependent.
The current spider chart has a huge spike in the legs category for two reasons:
  1. It shows legs in only one category. This feature request has been added.
  2. The volume for legs is generally higher, so the rest of the volume for the other categories seems tiny and not visible anymore.
If the spike for legs for e.g. 10K Kg was half as big for 10Kg volume for chest, and a quarter as big as for arms, that would be more reasonable.
