Shift your weight onto your elbows as you step back with the other foot and place your feet together. Hold until your form starts to fail or until you are no longer able to keep our abs pulled to your back. Step into the ball with one foot at a time. 1  Equipment notes.
For comparison's sake, most modern trucks manage between 5.5 and 6.5 mpg. For most long-haul truck drivers, an increase in fuel economy of 54 percent would equate to a savings of around $25,000 per year at current diesel prices.
Because todayâs EPA ratings are fairly realistic, thanks to the recent change in how theyâre calculated, these trucks should be about 1 mpg better in real-world use as well. But at $2.40 a gallon at an average 18 mpg (versus 17), if you drive 12,000 miles each year, that 1-mpg difference will save $94 a year.
