Summer shapeup 2011 - Firm up those thighs.
Posted by: RobWilliams on August 22nd, 2011
If you’re looking to burn calories and shape up your body, good leg exercises really are a safe bet. Because the muscles in the legs are so large, pushing them to a state of fatigue requires a lot of fuel, which burns a lot of calories. Activating these muscles on a regular basis can also boost your metabolism.
In an earlier post I outlined exercises that emphasize the hamstring muscles in the back of the legs. This week’s moves will target the quadriceps muscles in the front of your thighs. These muscles act to extend, or straighten, your knee joint, and assist in flexing your hip joint by bringing your knee toward your chest. To properly train all of the muscles that make up your quadriceps, it’s important to perform a variety of exercises that work the legs through a broad range of joint positions.
One note to remember about training your legs is to pay attention to the position of your pelvis and lower back during the exercises. Because a portion of the quadriceps musculature attaches to it, it’s common for the pelvis to be pulled out of safe alignment during the movements. By engaging the core stabilization muscles in your abdomen and lower back you should be able to prevent any issues and reinforce neutral pelvis and lower back alignment.
For any exercise be certain to gradually warm up your body and stretch the muscles you are about to train to prevent injury. Remember to breathe comfortably as you do the movements, and stop if you feel pain or in any way unwell.
Backwards hill running.
Any time you run uphill against gravity your leg muscles have to work harder to propel your body up the slope. In traditional running this overloads your glute and hamstring muscles as they extend your hip joint to push you forward. To target your quadriceps, try turning around and sprinting backwards up the hill. The extension required at the knee joint will recruit the lower quadriceps, which you’ll likely feel on your first trip up the hill. The number of repetitions depends on the length and grade of the hill you choose, but I’ll often recommend 100 strides, which could be 4 times up a hill that requires 25 strides to make it to the top, or 5 times up a hill that requires only 20 strides. Only count the uphill strides and be sure to pay attention for any obstacles when running backwards.
Toner hip flexions.
To strengthen the rectus femoris muscles in the upper quadriceps it’s important to perform resisted hip flexion exercises with your knee bent. Using a toner that’s anchored in a low position, with the other end wrapped around your foot or ankle, pull your knee up toward your chest against the resistance of the tubing. Attempt to keep your hips square and your spine in neutral alignment without arching or rounding your back during the movement. Holding a pole or railing for stability can be a good idea at first. Perform 2-3 sets of 15-20 repetitions per leg, gradually increasing the speed of the controlled movement.
Bench lunges.
I like lunges because they’re a very functional movement, and the endless variations can be used to emphasize different muscles in the lower body. The bench lunge is one of my favorites because of the elevated, flexed position of the rear leg, which recruits the large rectus femoris muscle. To do this exercise properly, place your rear foot on a step or bench that is below knee height. Your front foot should be far enough forward that you can keep your foot flat on the ground, with the knee at about a 90˚ angle at the bottom of the movement. Maintain a neutral spinal and body position as you lift and lower your body by bending your back knee toward the ground. Perform 3 sets of 12-15 repetitions per leg.
Body Science – Safe and effective outdoor training.
Although strength-training machines have their place in a comprehensive fitness program, I often encourage clients to train outdoors when the weather is good, using more bodyweight exercises. There are a lot of benefits to this, as well as a few things to watch for when training outside:
- Balance your program. For example, don’t ignore your back muscles.
- Watch the impact. Do as much exercise as possible on softer surfaces.
- Warm up and stretch properly. Avoid the tendency to jump right into the exercises.
Keep these tips in mind as you develop your own outdoor training program, or get an expert to help you create your own custom routine.
