What different exercises can i do for upper abs and lower abs?
I know that your body can get used to certain exercises if you do them too much, so i want to know what all i can do to work on my abs. All i know for upper abs is sit-ups and all i know for lower abs is crunches and leg-lifts. What all other things can i do? (I know core bridges but i’m also pretty sure that does both upper and lower) Thanks for any advice!! 
10 situps
10 V-ups (Touch your hands to your toes, but crunch your body so that they meet midway in the air)
10 lemon squeezers (Position yourself sitting up, put hands at side, and move your torso back into a laying position while extending your legs straight ahead. Now just row your legs to a bend while crunching toward them w/ your torso, then go back to laying position. repeat process)
10 back hypers (lay on stomach, basically a reverse cruncher)
10 Leg lifts (Lay on back, lift straight legs to 45 degree angle, then bring back to ground)
30 seconds of bicycles (Lay on ground, and mimick a bicycle pedal motion w/ your legs)
10 side crunchers each side
10 regular crunchers
30 seconds of flutter kicks (Lay on back, keep both legs straight. Lift them up bairly, now alternate between raising each leg a little bit and brining it back down. This one is tought at first, but after a week it will be easy. Try to think of being a swimmer while doing this one)
10 kick ups (Lay down, bring knees up toward chest, then kick legs upward to become straight in the air.)
10 side double leg lifts (Hard to explain, basically lay on side, and lift both legs simultaneously as high as you can. Will feel weird at first)
10 Forward Rows (Way too hard to explain, google it)
10 Russian Twists (Google it)
10 Scissor Kicks (Lay on back, spread leags apart in air, bring them back to center with one leg above the other, then alternate to mimick a scissor kicking action)
Finish with a bridge for however long you think you can do it.
Once this routine becomes easy, don’t up the reps, just do the whole routine twice. (Left a few out for explanation’s sake)
Then also do your run at night. Cut excessive fat out of your diet, but you can have a little still.
Do it and you will have some abs
hmm… theres a buncha things you can do… you gotta have a good diet and cross-training first of all (running, biking, etc.)…. after that, there’s the abs exercises…
do crunches
reverse crunches (lift your lower back off of the ground)
bicycles
leg raises
IF YOU HAVE ACCESS TO A GYM THESE ARE VERY GOOD!!!
crunches on an incline board, as you go on, you can add weights.
some gyms have a thing with a place for your hands and a think that has like a half bubble, on those you raise your legs, pretty straightforward.
anyway… thats about it…
but you have to equal out your abs with your lower back exercises because you dont wanna end up with a bad back.
Continue reducing your body fat and doing abdominal exercises. There’s no distinction between exercises for the upper and lower abs- a crunch or any other abdominal exercise works your entire set of abdominals. It’s just the case that people have more body fat around their waist, and as a result, definition of lower abs is more difficult.
The lower abdominals may be the single most popular subject among fitness enthusiasts today. This is due to the fact that having flat, tight, lower abdominals is a highly desired look, but a very difficult look for most people to achieve. Many fitness professionals insist that there is no such thing as “lower abdominals”, While others propose that exercises like crunches work the upper abs more and exercises such as leg raises or reverse crunches work the lower abs more.
Before continuing, first keep in mind that no abdominal exercise can “spot reduce” lower abdominal fat. Many people feel a need to perform special “lower ab” exercises, not realizing that the real reason they can’t see their lower abs has nothing to do with their choice of abdominal exercise, and everything to do with an excess of fat and possibly digestive problems
