ONE HANDLE - THREE GRIP
This handle position imitates the form and angles of your hand. This is the most ergonomic option, because the stronger part of your hand (the middle) does the most work while relieving the pressure on weaker parts of your grip. Ideal for high reps (12-20).
Just pull the strap to the other side so that the grip tails are looking upwards. You now have one half of a gymnastic ring! With the power option, the weaker parts of your hand get supported so you can lift or pull heavier weights. Ideal for 7 to 12 reps.
When using the ergo or power grip, just put your ring or index finger between the strap onto the ergonomic finger cavity. This increases the difficulty of gripping the handle, encouraging your forearms to work much harder. Note: Here you see a shortened strap!
