So the next progression for these exercises is to work up the leg to the calf. Sitting on the floor with our legs extended, we place the spikey ball underneath the inner calf (there are two calf muscles, one on the inside and one on the outside) and we are going to get Denis to massage back and forward and really work those little areas. This is a really good self-test exercise, you can find where the pockets of tightness are in the calf, some people feel it in different areas. So this is a really good self-assessment measurement and once again a great recovery exercise when you come off the golf course. As you know, most golfers get pretty tight in the calves when they play 18 or 36 holes, no matter where you play. If you are standing on the range for a long period of time this is just a nice way of breaking up your practice too. The tighter your calves are the harder it is to work your buttock muscles, and we want to work up in the trunk area, not pushing through the lower leg area. So we are giving our calf muscles a really good workout here. Invigorating the muscles and increasing the circulation and reducing that muscles tension. We then cross over to the left leg. Denis, what are you feeling when you are doing this exercise? I can just feel that the spiky ball is giving me a nice massage. And do you feel that any areas are tighter than others? Yes, especially on the outside of the calf with me. So once again you find that everybody is different, but you are getting a feedback system that is honing in on those tight areas. And if those areas are tight the first time you do the exercise there is a fair chance that those areas are going to get tight every time you play golf so you try to get them under control. Remember, the tighter the calf muscles are the harder it is to get the buttock, tummy and trunk muscles to work. By doing these exercises will give these trunk muscles the opportunity to fire correctly in the golf swing.
