I have a strange situation- no matter in how good shape I am, I always struggle with bent knee sit ups (crunches, too). I do overall body conditioning, I train for power, strength, flexibility, coordination, endurance… but these exercises are always hard for me. I really struggle in the later phase or the exercises, after 35- 45 degree angle. In the initial phase I don’t have problems, but after this it is really hard. I don’t have problems with other ab exercises- planks, leg rises, reverse crunches, Russian twists and you name it. What could he the issue for this?
 
With your feet floating or braced down by a pad or weight? What about wheel roll outs, can you go full plank and return. Much better core engagement over crunches.

I have pretty strong core IMO, but the problem is with the mentioned exercises. When my feet are braced down, I can do these exercises. I also can do them with straight legs.



Try anchoring your feet, could just been your centre of gravity.
I have easier time with anchored feet. I am much taller than the average person, so this can be the reason.

Any particular reason for the crunches? limited space or equipment , its ok to just like them more than other ab exercises too lol

There are just so many variations to hit the core more complex than crunches. The roll out, planks (shoulder taps added) , L-sits, dragon flags, , dead bugs, etc.

They only work the upper abdomen they it’s not an ideal movement bc your also using momentum by holding the back of the neck in a cracked position jerking forward .

Everyone is different but I don’t do anything but V sit ups there’s different variations i basic just lay flat arms extended fully and go up meeting legs half way as they raise up .

Basically it’s …….

( V-ups engage and strengthen the core muscles, including the rectus abdominis, obliques, and hip flexors. This improved core strength is essential for stability, balance, and everyday activities. )

You don’t even have to as many because your actually working the entire mid frame at the same time , doing many crunches as fast as you can is kind of useless in comparison, it’s much harder to do slow crunches and it’s not recommended doing those movements .

No, no, I don’t have super large empty spaces around me in recent time, but I have enough space for ab work. I am just surprised to find that they are so hard for me, despite being able to do many other ab exercises.

Are these V sit ups also called Jack knives? If yes, I think that they are great exercise. Very heavy on the mid section and because of this you do not need to do many of them. Reps in numbers, close to weightlifting exercises are more than enough.
