A swiss ball exercise for a tighter waist

Get a swiss ball and do lateral crunches ; this exercise is particularly effective for the obliques and abdominals because you have the possibility to work on an extended range of motion.

This increased range of motion means a better work of the muscle fibers because different angles of the movement are emphasized : you start with a pre-stretch, the side of the body is in full extension, then you crunch and squeeze the obliques.

Focus on the pre-stretch, and then focus on squeezing the muscles during the flexion.
Do 3 sets of 8-10 reps for each side everyday for 10 days and you’ll see…
Do not forget to do 3 to 5 deep abdominal breathing between each set. You’ll get more energy in the same time.
