I finished my first workout yesterday, and am completely sore all over today. Should I just workout through the soreness?

Glad to hear you are trying a Fitrex workout. It is normal to experience some soreness when starting a new program. Some things that will help alleviate soreness are warming up properly before training, drinking plenty of water, and doing a little more stretching after you exercise.

How sore is too sore to work out? Nobody can really tell you what to do because we all have different physical responses and pain tolerance levels. If your soreness is more of a sharper type of pain or if it limits your ability to move around normally you probably need to take an extra day off and do some light cardiovascular work and stretching. On the other hand if you can move around normally but just feel a little tightness or if you flex the muscle and it aches a little you can go ahead with your training program. Also, as you workout you will actually help to stimulate recovery and help the soreness go away faster!

Here is a very important piece of the puzzle when doing your workouts:
make sure that you can finish all of the sets and reps with the prescribed weights WITHOUT a training partner helping you through the last few reps. These are called forced negatives and will create much more soreness. The Fitrex program philosophy is all about a positive completion of your sets and reps. If the program asks you to do 10 reps with 100 pounds, you should be able to perform these reps. And, if it asks you to perform 3 sets of 10 reps at 100 pounds you need to be able to complete all 3 sets! You need to decrease the weight even if on the last set you could only do 8 reps. You need to increase the weight if you could easily perform all 3 sets of 10 reps. Again, this balance of sets, reps and weight needs to be based off a positive completion. This should help you to not become too sore in your workouts!
