When I upped the doseage recently my weights shot up and I found I was training at a much higher intensity doing more sets and lots more weight! I was even doing extra arm work twice a week! Unfortuately after about 2 weeks it all started to catch up with me to the point where everything was ultra sore and wasn't recovering before the next workout! Weights even started to go down!
Since then I have taken 4 days off weight training completely and all soreness is virtually completely gone! When I start back tomorrow I will be a little more cautious and do far less overall workload but concentrate on pushing the weights up and with good form! Constant monitoring of how your body is responding to the stress is often the key to your success in this game!!
