Yes! Working out again will actually help your sore muscles feel better due to the increased blood flow to those muscles. During the first 2 weeks of your new workout program you will be the most sore and then it should subside a bit. You don’t have to be super sore after your workouts to see results, being TOO sore can actually be a bad thing. If you notice you are getting TOO SORE, like can hardly walk kind of sore, lighten up your weights a bit until your body adjusts.
