My GAIN Fitness App updated to include the option to buy a Shockwave pack this morning. Does that mean something is coming soon? I'm excited about the possibility!
Since I can't get the SW until the new one comes out, can someone tell me what is PSR and ELECT and how to do them for the Heavy Duty regimen? I've scoured the forums and the more I read, the more I can't distinguish between the two.
