Design a split routine -- You don't necessarily need to work every major muscle group in each workout. One day, work only your upper body for 20 minutes and then finish with 10 minutes of cardio. The next workout, do lower body and finish with 10-15 minutes of cardio.
Perform weights and cardio on separate days -- One day focus only on cardio for 20-30 minutes, the next day weight train for 20-30 minutes. A few days later, yoga or Pilates for 30 minutes. It's an excellent way to balance your routine and stay invigorated.
Split your video tape workout -- Lots of people love to exercise using video tapes and dance aerobic tapes. Who says you have you do it all in one session? Split the tape into two days (assuming it's an hour tape) and slightly increase your intensity level each day. You'll still get great results.
Weight/cardio mix -- One good short duration workout method is to perform one weight training exercise followed by three minutes of cardio. Then, back to a weight training movement, then three minutes of a new cardio exercise. Keep repeating without rest until you achieve your 20-30 minute goal.
Walk briskly at lunch time three days per week for 30 minutes -- Don't get caught up in the fact that it's not enough. We're looking for consistency -- which will ultimately help you lose some fat and get fit.
No time for a 30 minute walk in one session? Split your workout into two separate times during the day. Walk in the morning for 15 minutes before work and then again at lunch or right after work. Studies show that it's just as effective one 30-minute session.
