Try the 12 Second Sequence Workout! You get a good strength and conditioning workout without getting large bulky muscles. You also increase your endurance while losing weight. This workout should only be done twice a week, with 2 days inbetween your workout days. You will work every muscle group (Bicepts, Tricepts, Chest, Abs, Shoulders, Neck and Traps, etc.) You can use ankle weights and dumbbells for this workout. The ankle weights (plus squats) will work your lower body, while the dumbbells work the upper body. The workout generally takes about 30 to 45 minutes depending on the number of exercises you do.
You always use the proper form when doing the exercises, in order to get the maximum out of each exercise. For example: if you are doing curls, you do the lifting to a very slow 10 second count. When you get to the point of maximum resistance, you hold the position for 2 seconds, then you lower the weights again, to a very slow 10 count. Each exercise is done in the same way. 10 seconds up with the weight, 2 second hold and 10 seconds down with the weight. You never do more than 5 reps to each set, and generally you don't have to do more than 2 sets of each exercise. Start off gradually with only 1 set. You will be sore! So build up gradually (over a couple of weeks) to 2 sets on each exercise. When you are finished with each exercise (curls, bench press, etc.) only wait 1 minute to 1 and a half minutes before you move on to the next exercise. ALWAYS EXHALE ON THE LIFTING OF THE WEIGHTS AND INHALE ON LOWERING THE WEIGHTS, otherwise the exercises could raise your blood pressure. NEVER HOLD YOUR BREATH WHILE LIFTING WEIGHTS. Again, it can raise your blood pressure considerable.
When you do the exercises in this manner, you will be using stabilizer muscles in addition to the muscle group you are trying work. Generally, within two to three weeks you will be losing weight, firming up, building strength and endurance. You also have to eat right for this to work. Your diet should consist of the 40/40/20 ratio- 40% Protein, 40% Carbs and 20% Fat. Avoid real starchy foods at night, eat more vegetables and try to eat small amounts, but eat every 3 hours- to jump start you metabolism.
