What workouts burn more calories than crunches?

If you want to be series about working out and toning your core than do your usual 30-50 crunches than lay on your back. this is weird but have one of your friends stand rite over your head facing you grab onto his ancles lift your legs and let him push them back down. dont let your feet get below 6 in from the ground and repeat this process until your abs hurt like hell. Than lay down and put your hands behind your head and pettle your feet as if you were riding a bike. also if you just lay on your back lift your upper body up 6 inches and your legs up 6 inches and hold that stance for 1 minute its called (cockroach) or if you want to make a game out of working out than get 3 people together and a deck of cards. 1 person will be the card dealer until the deck is used. that person should let the cards sit in a pile face sown and flip on card over. Say the card he fliped was a 9 whoevers turn it is has to do 9 crunches than the card dealer will flip the next card. Say its a 2 the secound player will do 2 crunches. you repeat this process until one of you wimps out and says that you cant do anymore. Dont worry I learned this one in boot camp it works!!! and its a chance to show your friends off (= please comment me and tell me if my advice worked for you

just both I would like abs not going so well I do run sometimes too

I don’t think you need to do them are you trying to get fit or trying to be skinnier?
