I’ve seen people wrapping the bands around themselves in a kind of figure 8, but I couldn’t get that technique to work for me.
Instead I take the looped band, put it over my head and grab as far up as I can on the loop.
This creates a bit of slack band, but it doesn’t usually get in the way
Once the band is in place,
draw your belly button in to activate your core muscles and lie flat on your front
Extend your arms to press your upper body upwards,
Pause for a second and lower your upper body back down to the ground,
Allowing your chest to touch the floor.
Repeat for maximum number of reps possible with perfect technique
