My weight loss took off again and the pounds started dropping again. If you're a beginner, using more muscles means getting fatigued sooner -- which will result in burning fewer calories. This was a big plus. They can be judgmental as well. Continue alternating in this way until you reach zero.

Here's the lowdown on what you can expect from some of the machines you're likely to find at your local gym. The treadmill burns the most calories of any of the cardiovascular machines available at most gyms, says Alexander. You can expect to burn about calories per mile, walking briskly. Stamford notes that a treadmill can be adapted to many different fitness levels by increasing the speed from walking to running or by adjusting the incline.
But even walking may be too much for someone who is overweight and has joint pain. Every time your foot hits the ground, says Alexander, "the impact forces are 3. Since a treadmill is moving under you, the impact may be slightly less than that. One more thing to keep in mind: Treadmills can pose a real balance challenge for new exercisers or those who haven't worked out in a while, says Matthew Vukovich, exercise physiologist and associate professor at South Dakota State University.
These machines pack a little less punch on the joints, and either can be a good alternative to the treadmill, says Vukovich. Because you use them in a standing position, you're using lots of muscle mass, so the calorie burn rate is still pretty high. Elliptical machines with arm components can further increase the numbers of calories you burn, says Stamford. All our experts agree that the stationary bike offers the workout with the least impact on the joints.
People with knee pain are often steered toward these bikes, since the impact of body weight is not a concern as it is on a treadmill, elliptical trainer, or stair stepper.
But to avoid knee strain, you must make sure the bike is adjusted to fit your body, Vukovich says. Most people sit too low, meaning their knees flex too much as they pedal. This can put too much pressure on the knee and result in soreness, warn Vukovich. The stationary bike is a less intense calorie-burner than some of the other machines. You'll need to pedal four miles to burn calories, says Alexander.
Rowers are more advanced cardiovascular machines. Because you must push with the legs while you pull with the arms, rowers require coordination. They also you require you to engage your core abdominal muscles to support and protect your back.
Because they use so many muscle groups, rowers burn lots of calories. But this machine has several red flags for a beginning or unfit exerciser. Extra weight often comes with back pain , and this is not a machine you want to use if you have back issues, he says. Choose a machine that feels right. If impact is a problem, the stationary bicycle may be a better choice than the treadmill. More muscle use equals more calorie burn.
The basic rule of thumb is that the machine that exercises the greatest muscle mass burns the most calories. There's a flip side of that coin, too: If you're a beginner, using more muscles means getting fatigued sooner -- which will result in burning fewer calories.
Try using a pre-programmed workout that includes variations in speed and intensity. When it comes to fat loss, slow and steady loses the race. More intense training -- in shorter bursts -- burns calories more quickly and burns more fat overall. And unlike long, slow cardio sessions, intense training keeps you melting fat even after your workout is over, says Martin Rooney, director of the Parisi Speed School and author of "Ultimate Warrior Workouts.
For fat loss, the two best exercises to eliminate from your routine, says Ballantyne, are "the fork to mouth and the ounce curl. Put down the tortilla chips, and try these five high-intensity training strategies to torch fat fast. Men and women who did hours of cardio over the course of a year lost an average of only five pounds.
Interval training -- bouts of high-intensity exercise alternated with short rest periods -- not only burns more calories than traditional cardio training, but also boosts your body's ability to fry fat through hormone production.
Not only are interval workouts shorter than traditional cardio training, but they also make you fitter in fewer sessions, he adds. Steady-state works by increasing the oxygen delivery to your heart and lungs. Intervals, however, work on your muscles, helping them use oxygen more efficiently so your heart doesn't have to pump as much to make them perform. Jump on a stationary bike or onto a treadmill, and start your own interval training regimen with this guide from Ballantyne:. Start with a regular warmup.
When you've finished that, pedal or run at a rate that's 20 percent harder than your normal cardio intensity. After 30 to 60 seconds, bring the intensity down to a rate that's half the intensity of a normal cardio workout. You want two extremes: Alternate periods of 30 to 60 seconds of hard work with 30 to 60 seconds of easy pedaling or easy running for six to 10 intervals to complete your session. As this gets easier, increase the intensity of each interval, work longer during the hard portion, shorten your rest periods or add more intervals.
If you haven't sprinted since a coach was blasting a whistle in your ear, you're missing out on a natural but extreme form of interval training that can pay dividends for more than just your legs.
They have tremendous arms and shoulders, too," said Nick Tumminello, director of Performance University. A quick caveat, though: If you're not used to bursts like these, Tumminello says, it's easy to pull a hamstring, halting your training -- and your results.
He suggests following these tips to start safely. Sprint on a hill. The impact on your joints is lower, Tumminello says, which can help you avoid injury.
Live in a flat area with no hills? Instead of the drag race approach, begin your sprints by speeding up from a jog. At a local track, jog the curve, then sprint 10 to 20 yards of the straightaway. Continue interval sprinting in this way. To maximize benefit and lower injury risk, keep your sprints on the shorter side -- no more than 50 yards per sprint.
This will help you maintain a high intensity throughout, says Tumminello, and prevent your form from breaking down, which can lead to injury. To increase the overall results of your sprint workout, increase the number of sprints instead of going for long distances. When you're starting out, perform a sprint workout just once per week -- you'll be surprised at how sore the workout makes you, even in the abdominals.
Once you're used to the stimulus, Tumminello suggests bumping it up to only two sessions per week, mixed with other gym workouts. Allow at least two days of recovery between sprint workouts. You don't have to run, bike or perform any traditional cardio exercise to get high-intensity, fat-burning training. By pairing strength exercises that work opposing muscles, you can build muscle while keeping your heart rate high, maximizing fat loss.
During the lunges, the arms and back rest, while the legs rest during the pull-ups. Jack uses such exercise pairings to do escalating density training, an interval protocol with a built-in challenge. To try this challenge: Choose two exercises that use opposite movements or work completely different muscles -- pair a pushing exercise with a pulling exercise or a lower body move with an upper body move.
As an example, consider a dumbbell bench press and an inverted row. For each exercise, choose a weight with which you can perform 10 reps. Alternate between the exercises, performing just five reps of each move, with the rep weight, in each set.
Rest as needed between sets and pairs so that you can complete each set of five without failing. As with cardio intervals, strength intervals like these won't work if your reps aren't high-intensity. Continue alternating between the exercises for a set time -- 10 or 15 minutes, for example -- keeping track of how many total sets you can do. In following sessions, try to beat your score by finishing more sets in that time or by finishing the same number of sets but with tougher weights.
Density training sessions are great to add to the end of a traditional strength training workout, Jack says.
