Youre just working muscles that you normally dont work
Yes, you get abdominal muscles.
Never, you always have working muscles. Eg: your core muscles work to keep you standing/upright.
Hamstrings,...
Abdominal muscles, among others.
you might have RLS, or restless leg syndrome. or if your younger and still growing, your legs are just growing their muscles. try to sit still for 30 minutes. and drink some fluids
You can stretch out your muscles, build muscles by doing sit ups, crunches, push ups, etc. I myself use one in morning and at night to do my crunches. The lift off the ground puts more stretch to your muscles so it benefits using one.
recumbent bikes allows you to sit in a seated position with a back rest while the upright is more like a traditional bike and works more muscles like your abdominal muscles to help stabilize you core when working out.
By working your whole body. L-Sit is a very demanding exercise that uses your whole arm muscles and your core muscles. This is why a strong core and strong arms lead to better success in the L-Sit. You can strengthen your abdominal muscles with exercises like plank, hanging leg raises, dragon flags etc., and you can strengthen your arms with exercises like chin-ups, pull-ups, dumbbell curls.
Sit ups tone muscles, but you can lose some of your stomach just by weight loss. If you still need to tone up, just try contracting your stomach muscles when you're sitting down. Try to contract them for as long as you can; you should see an improvement after a week.
The best sit-up exercise equipment options for home use include ab rollers, sit-up benches, and stability balls. These tools can help you effectively target and strengthen your core muscles while working out at home.
