This attaches from your feet to a band or cable, allowing you to resist your core in a way that emphasizes your lower abdomen and hip flexors.
Strength BELOW the belly button is a common weak point. In the ATG system, we work toward at least half of bodyweight for 20 reps, getting the hamstrings to cover the calves on each rep.
While this is a potent exercise for athleticism, it's also a favorite of MOTHERS for rebuilding strength after having babies.
In elderly I've noticed the lower abs and hip flexors are particularly weak, likely due to not sprinting anymore. This can help you get that youthful pep in your step back!
The lower abdomen is opposite of your lower back, so I've also found this helpful for a more stable core, resulting in less lower back pain and injuries. No studies have been done on that yet, but the theory is simple: no weak or tight links! With greater ability around fragile areas, you wind up with less pain and greater athletic potential.
This material won't break down like the other low ab straps on the market do. I know because I've tried them all and we used to make the same style. I was finally fed up with the breakdown, so we made them in a different material that's incomparably more durable.
