Twisting Floor Crunch Instructions

  1. The twisting floor crunch works the abs and obliques. Position a mat on the floor and lie down on the mat flat on your back.
  2. Pull your left leg up until your knee joint is at around 90 degrees.
  3. Now take your right leg and rest your ankle on your left knee.
  4. Start the exercise by touching the side of your head with your fingertips and raising your shoulder blades slightly off the mat.
  5. Crunch up, bringing your left elbow up to your right knee.
  6. Slowly lower back to starting position without letting your shoulder blades touch the floor.
  7. Repeat set for the opposite side of the body.

​Exercise Tips:

  1. Never let your shoulder blades touch the floor throughout the set.
  2. Try to bring your elbow up as high as possible using your abs only (no swinging!).

I have been on a weight loss diet for 6-8weeks now. I have been doing quite a bit a weight training. Now that i have lost nearly 14kg and building muscle mass, i would like to change protein shake. I have been having protein 90+, which is a low fat high protein shake. Which preotein shake can you recommend for building mass but also weight loss, not a very high carb or fat shake.
