Lying Floor Knee Tuck Overview
The lying floor knee tuck is a variation of the abdominal crunch and an exercise used to isolate the muscles of the abdomen.
The lying floor knee tuck is a flexion based exercise which keeps the lower abdominal muscles under constant tension during the entire range of motion.
Lying Floor Knee Tuck Instructions
- Lay supine in a relaxed position with your legs straight and your hands underneath your low back for support.
- Raise the knees toward your forehead while contracting your abdominals and exhaling.
- Once your abs are fully contracted and your knees are slightly above parallel, slowly lower your legs back to the starting position.
- Complete for the assigned number of repetitions.
Lying Floor Knee Tuck Tips
- Exhale hard like you’re blowing out candles on a cake and hold the contraction for a second in order to improve mind muscle connection.
- If your lower back bothers you during this exercise, choose more anti extension and anti rotation based movements.
- Avoid putting the hands behind the head as this can lead to excess strain upon the neck.

This website is awesome and I will continue to use it
Ah, helpful information. I was not keeping my knees together.
Not every kind of xeircese burns fat. Each kind of xeircese has a different effect. For example, there's a precise way to do aerobic / cardio xeircese so that you're sure you're burning the extra fat in your body and not just the sugar in your blood. If you want to be a perfectionist ask someone who studies sports sciences or medicine for more details.
Can you provide more information on this? I do to know anyone to ask, but I NEED to know I am getting the most fat burning possible out of my work outs. I am a beginner - have been going to the gym for about 5 months now, the first 3 months I went 5 days a week and the last two I have been going three times a week. Although I have developed tendinitis in my left shoulder and I start therapy next week. This only increases my need to burn as much fat as possible while doing cardio or any other exercise!
