Service members have crazy schedules, which makes it hard to find time enough to work on your physique. Most of us have only about an hour to spend each time we hit the gym. Typically, the routines we do in that brief period consist of using free weights and a few workout machines.
Many people who step foot in the gym are there to lose weight. They'll use the various isolation (or single-joint) machines believing that if they use every machine the gym has to offer, they'll start to lean out. The unfortunately fact of the matter is that not all the machines in the weight room burn a lot of calories when you hop on and start repping.
To burn the most calories in the shortest time, most gym professionals recommend focusing on compound movements — exercises that require more than one muscle group to move a weight, like pull-ups or dumbbell presses.
So, which machines should you avoid if you want to burn fat?
1. Leg extension machine
Leg extensions help bulk up your quadriceps. Most of these machines require you to sit down and enjoy yourself as you rep out the sets. This is a very isolated movement — and that's not the best way to challenge your body and burn fat. Instead of sitting on the machine to work on your legs, consider standing up and doing some non-weighed squats.
2. Calf raise machine
Yes, the calf-raise machine will bulk up your calves up — but it won't burn off those unwanted calories and lean you out. There are plenty of other options when it comes to working out your calves. The video below will show you a few techniques that introduce compound movements to a calf workout.
3. Bicep curl machine
On this machine, a patron sits down and works their biceps against resistance while in a static position. Even if you're trying to work on your arms, the process of selecting, moving, and returning free weights will help you burn a little extra fat.
4. Seated tricep extension
If your goal is to build massive triceps, then you'll want to add a few tricep-related exercises to your routine. However, if you're also looking to burn some extra fat in the process, you might want to conduct your training in a stress-loaded, standing position.
5. Seated abs crunch machine
There many ways to get a solid ab workout — but you'll find that very few fitness trainers recommend that people take a seat in ab crunch machines. Those machines are fine for beginners or people with medical conditions, but everyone else should strike this machine from of their minds and replace it with these:
