The US Army and Navy are phasing out sit-ups by 2020. The Canadian Armed Forces has done away with them already. Tony Horton, creator of the famous P90X has banned sit-ups and crunches from his routines and Pete McCall, author and health and fitness expert referred to them as “an antiquity of exercise best left in the dustbin of fitness history”.
Why the Change?
Sit-ups put too much pressure on the spine by squeezing the discs. Overtime, the discs can bulge, pressing the nerves, and cause hernia.

Instead of sit-ups, the US Navy will incorporate planks.
Planks stabilize the spine and that’s what the core is supposed to do.
