Interestingly, sit ups actually put less pressure on
the neck than crunches.
Not exact matches
Crunches and sit - ups cause more risk of injury to your lower back, and your
neck, and less reward for your abdominals
than safer things you should be doing.
However, the edge went to planks because it is sometime tough to properly perform
crunches — people use momentum and involve other muscles that should not be stressed (have you ended with a
neck pain rather
than abs sore?).
