Ever do an ab exercise and wonder why it doesn't feel like it's actually working your abs?
Your position relative to gravity might be the missing piece.
Here's the concept: gravity needs to be working directly against the muscle you're trying to target.
Hold a dumbbell down by your side and your shoulder barely has to work.
Hold that same dumbbell out in front of you, and you'll immediately feel your shoulder kick in.
Nothing changed except the position of the weight relative to gravity.
The same idea applies to ab training.
A standing ab exercise puts your abdominals in a position where gravity isn't loading them much at all.
Move onto your back, and gravity now loads the abdominals directly.
One note worth knowing: lying on your back for ab work also loads your hip flexors.
If that position causes you pain, a ball crunch is a great substitute since it targets the abdominals without pulling the hip flexors into the equation.
Have you ever switched up an exercise position and immediately felt the difference?
