Ok, this is a bit of a ramble, so I apologise - but it may also be a simple answer that I am old and fat.
Recently I seem to have a bit of a problem when netting of pulling or tweaking muscles really, really easily, and it happens fairly consistently and in various parts of my upper body.
Currently I've done something to the bicep / deltoid area of my left (bowling) arm, it recovers over a week of normal activity, then as soon as I bowl again it pulls and becomes very painful from the very first delivery. In addition to this, after only an hours bowling last night I've got pain and stiffness right at the top of my spine, where it joins the neck.
Is it simply age?
Do I need to warm up a ridiculous amount (certainly more than I do) - is there a definitive guide for bowlers to warm up from?
Do I need external ointments and compression gear to avoid this?
Do I need to do some regular upper-body weight training to strengthen and toughen the muscles?
Is there something I should add to my diet to aid muscles?
I'm particularly worried about the bicep on my bowling arm, it 'goes' every time I net. Should I rest this for a couple of weeks, or should I exercise it?
There is only so much Tiger Balm I can apply!!!
