This is a quick post to remind you all of the importance of warming up before you do any exercise as its now coming towards the winter months. When you exercise after being static during day your muscles can be quite tight and if its cold this can be double trouble! Think of an elastic band left in the cold all day. If you suddenly put it under any load it can easily damage or even snap. Your muscles are similar. So whatever exercise session you are going to do get warmed up! An example is as follows. 5 min light jog on treadmill. 2 sets free standing squats of 30 reps 2 sets 15 push ups 3 min skipping. You can adjust this accordingly but do at least a 10 min warm up workout. You will be glad you did! Also wear thick hoodies when warming up! Dont be that guy who walks in the gym in winter with his vest on and wearing his wooly hat because he said he is cold! Hope this helps someone. Good luck.
