Exercise at night, lie flat and lift your legs 30 degrees. The thigh root is the most uncomfortable, and there is no feeling in the abdomen. Can I exercise my abdominal muscles like this?
My six-pack abdominal muscles are the envy of people around me. The method is simple. Junior high school physical education teacher taught me not to get up in the morning, lie flat, keep my feet five centimeters away from the bed, slowly raise them to 90 degrees, and then slowly put them down to five centimeters away from the bed (PS; Slow down! ! ), stop for three seconds, then raise it, so repeat it ten times a day, and it will have obvious effect in two weeks! !
