How do I not get so tired in cardio?

Why do I feel tired after my workout? Did I lose my endurance?

• My goal is to overall tone my body (not lose weight...or at least alot...dont' need to) AND most importantly, lose my beer belly (genetics, althought i'm a very slim girl) and tone it completely. I started my workout routine again mid May by doing swimming aerobics 2x/wk. With swimming aerobics, I slowly started doing cardio+strength training about 1x/wk - arms, shoulders, squats/lunges, ab workouts (bicycle) in June. And now this month, I do swimming aerobics m/w, and cardio+strength training t,th,f. Last week i did cardio+strength training on 3 consecutive days - body was fine. I missed 4 days (migraines) and I feel kinda bad and soo anxious b/c I'm afraid I might not get my tummy lean by the end of the month (which is what I'm working on). I went to swimming aerobics today and my body feels so much better but TIRED. I usually do some ab/butt workouts and some strength training afterwards but when I tired tonight, my body just felt tired...I'm worried and I hope this isn't a step back. Did I lose my workout endurance? :(

• Answer:

  It's probably just your body recovering from your migraines. Still go to work out, but cut down a bit for the next couple days, then gradually climb back up to where you were before. Your body just needs a rest, thats all. Give it what it needs or you'll pay later!
