If you think rowing only works the arms and back, think again. “The machine utilizes more than 80 percent of your muscle mass, taking the body through a dynamic range of motion,” says Crosby. “By spreading the workload over the entire body, you’re able to work at a higher intensity or go longer.” Either way, you’ve just added more calorie burn to your workout.
The brain is composed of a network of neurons that transmit signals by propagating nerve impulses. The propagation of this impulse from one neuron to another is typically controlled by neurotransmitters, though there are also electrical pathways between some neurons. Neurotransmitters can inhibit impulse firing (primarily done by γ-aminobutyric acid, or GABA) or they can excite the neuron into firing (primarily done by glutamate). A neuron that releases inhibitory neurotransmitters from its terminals is called an inhibitory neuron, while one that releases excitatory neurotransmitters is an excitatory neuron. When the normal balance between inhibition and excitation is significantly disrupted in all or part of the brain, a seizure can occur. The GABA system is an important target for anticonvulsant drugs, since seizures may be discouraged by increasing GABA synthesis, decreasing its breakdown, or enhancing its effect on neurons.
When you are new to exercise, you can start your biking workout program with a simple test. Use your odometer (or a GPS watch or smartphone app) to see how far you travel when you bike for 30 minutes. Jot down the number in your workout journal and set a goal to decrease the amount of time it takes you to ride that same distance and route. As your fitness level improves you'll be able to log more miles in less time and you'll burn more calories in the process.
While it’s important to eat your vegetables, everything is fine in moderation. If you have a sweet tooth, eat a small portion of candy or dessert once in a while. If you always deprive yourself, you might be more likely to binge. You also need to be honest with yourself about what you are eating, says Frank Overton, owner and founder of FasCat Coaching in Boulder, Colorado. “There is so much crap that people have in their diet that is just out of habit,” he says. “Try to reduce or cut out soda, sugar, and junk food. Have a few less beers each week, or drink wine since it typically has fewer calories.”
