Are you frustrated because you're not seeing the results you want from your workouts? It may be because your program hasn't changed in a while. While our minds love the status quo, our bodies need to have challenges! In an eight week program, it's important to increase the weights up one level every couple of weeks. Otherwise, the body knows it doesn't have to work as hard as it did in the beginning to do the exercises. So you don't get the positive changes you're looking for - you've gotten stagnant.
Also, at the end of eight weeks, you need to get a new program. Build on the skills of the first program, but make things more challenging. If you were doing squats with biceps curls, try doing the squats on a BOSU, and do a different upper body exercise. That increases the challenge to your muscles, balance and core.
As you go through each program, the weight should go up and the reps should go down, so you cycle through the endurance fibres into the strength fibres in your muscles. That way, you'll have a well-rounded program that challenges you constantly - and gets the results you want.
