If you move quickly from one station to the next resting no more than 1 minute between circuits this will also add a cardiovascular element to your workout. For people who are looking to drop excess body fat while toning and strengthening this is an excellent training principle to add to your fitness arsenal.
“An exercise “circuit” is one completion of all prescribed exercises in the program. When one circuit is complete, you begin the first exercise again for another circuit. Traditionally, the time between exercises in circuit training is short, often with rapid movement to the next exercise.” is the Wikipedia example of circuit training.
Following is one example of a circuit I commonly use:
1. Sumo dead lifts
2. Standing cable ab crunches
3. Triceps push-ups
4. Bench crunches
5. Hanging leg raises
After completing 4 to 5 of these circuits not only will you sweat profusely but you will have adequately addressed the issues of core-strengthening, over-all body conditioning and added a cardiovascular component to your workout as well.
You should be in and out of the gym in no more than 20 to 30 minutes. This is an excellent way to train during those days when all of your other commitments just won’t allow you to have a solid hour to dedicate to the gym. You can always add a walk with the kids, a little extra pool time or ice-skating, etc when the weather permits allowing for fun with the family before or after your time in the gym.
