I woke up with sore lats

I did back and biceps today but I woke up with sore lats. Dame I guess my body is still not  accustom to the heavy weight. When you work out on one body part (chest) like I did yesterday and another body part gets sore It's because some other muscles came into play to assist with the heavy movement. Then to add insult to injury I had to do back today. All in all it didn't effect me so it's all good. you know the drill thegymethusiast@gmail.com blog you later.
