Frog Sit-Up / Butterfly Crunch

General and Specifics

• the focus is on the upper abs area
• in comparison to the usual Crunch, this is a little harder to do
• the inner thighs are also slightly stretched during the abs workout

Starting Position

• lay your back on the floor or a mat
• bend the legs, so that the soles touch each other
• pull the feet towards the bottom a bit
• the knees point outward and are as close to the floor as possible
• hold the hands at the temples, cross them in front of your chest or stretch them out

Correct Execution

• brace the abs and lift the upper body
• always hold the head in extension to the spine
• the range of motion is smaller than in the usual crunch
• the lower back remains on the floor and does not lift off
• hold the contraction for a short moment
• afterwards, let the upper body sink down and repeat
