If I were doing the same thing day after day, I'd get pretty bored too. Exercise should be fun because when we enjoy doing something, we look forward to doing that something each and every day.
How about mixing in some daily walks with the Shred DVD ? Or try another DVD. No one says you have to do the Shred every day for 30 days. Do other workouts that mix up your routine.
I enjoy taking daily walks as part of my regular exercise. Why not take a walk ? There are members who will tell you how they lost 100+ pounds just by walking and watching what they ate. How about getting a set of resistance bands and doing some strength training exercises while you watch your favorite TV shows ?
You could ride a bike, take dance lessons, learn a martial art, play softball, roller skate, work in your yard, swim, play tennis, hike, etc... it's all good.
