The good news is that if you short of time, you absolutely CAN fit an affective workout into 30-minutes. And if you are exercising for weight loss, researchers found that a 30-minute workout is just as effective as one that takes an hour. What does a full-body workout look like?
Start by jogging one mile to your gym. If it is close enough to your house great; if not, park a mile away and jog in. Then take 5 minutes to warm up the muscles you are going to target in your workout with some dynamic stretching.

Now your 30-minute clock starts, now take 12 minutes to work the following body parts:
Depending on your goal, this is the number of repetitions (for each exercise): Building strength and muscle size, do 4 to 6 reps with heavier weights; for general fitness, 12 to 15 reps with moderate weights; for fat burning and endurance, 20 to 25 reps with lighter weights.
