The Dead Bug, aka Happy Baby, is a core move you should be doing

Posted on by
The Dead Bug helps train the core muscles to be strong and enhance spinal stability.

Obtaining a strong core can be surprisingly easy. Even better, there are excellent exercises that you can do lying on your back, using a simple band as a progression. One of the best exercises taught by strength and team coaches, yoga teachers, Pilates instructors and the sports medicine community is the Dead Bug, also known as Happy Baby. The base move is an isometric bracing action, as if you’re readying to take a punch to the belly, which promotes core stability and strength in your torso. Progressions or regressions are then tailored to your abilities and fitness level.

In Dead Bug, the reciprocal arm and leg patterns, like a dying bug on the ground, resemble motor skills like walking, running and swimming. (Or a happy baby lying in a crib, arms and legs akimbo)

The key muscles you work during the Dead Bug primarily focus on the core musculature, the powerhouse of the body. Picture the muscles forming its structure of floor, walls and ceiling. This includes the erector spinae, the deep low back muscle known as multifidus, hip adductors, rectus abdominus and the internal and external obliques. Exercises like this enhance spinal stability by training the deep postural muscles that protect you while you play the sports that you enjoy. Core stability, or trunk stiffness, allows you to transfer force to your limbs so that you throw, strike, kick, push, swing or run better. In other words, all motions are generated from the core and are translated to the extremities.

Our nervous system prefers to move with the most efficiency at all times. If your core is weak, most likely your brain will want to make it easy for you, and compensate. But over time, the compensation will create greater degrees of wear and tear. For example, slouching and leaning on handles on a stair climber or treadmill will make it much easier. But the wear and tear is more likely to be around your neck and shoulders. This can result in even worse posture, as a weak core encourages slumping, which tips you forward and off balance.

It’s often thought that repetitive flexion and extension exercise, like the good old sit-up, are a good way to train the core. But these muscles are rarely used in this way because they are more often used to brace while stopping motion. Researchers found that disc injuries can develop through even low-compressive forces with excessive bending and extending. An isometric exercise like the Dead Bug helps train the core muscles to brace under heavy loads, which helps stabilize the spine and in turn prevents buckling.

Dead Bug/Happy Baby

Start by lying on your back. Your spine should not be arched or flattened. Draw the abdominals in to assume the neutral position.

Reach your arms up. Lift your legs off the floor, holding a 90-degree angle at your hips and knees.

Move your arms back and forth (like a baby reaching up to play with a mobile) Duration: 30 seconds. Progression: Extend your arms and legs towards the floor, creating longer levers to increase the level of difficulty. Click on the video to see more progressions: vimeo.com/389162099.

Are you doing it right? How to do standing bicep curls

Posted on by

If you needed to work on your balance, standing on one leg, say for 30 seconds, is a good exercise. A good cue would be to imagine your stance leg as a wood post, or that you cement your foot into the ground. Besides helping improve your balance, the muscles of the lower leg play a role in helping you stand on your leg. An exercise like this, standing on one leg, offers a practical carryover to a real-life situation where you just might need to be strong on one leg. A goal of strength training is not only to improve strength, but also to improve function and prevent injury.

The barbell or dumbbell bicep curl is an arm strengthener, common in resistance training. The action involves elbow flexion, or bringing the hands toward the face. Most people stand with their feet side-by-side, or parallel, to perform them. Front-loaded exercises, like the barbell biceps curls, shift the body’s center of gravity forward, outside of your base of support. What typically ends up happening is that most people sway their trunk backward to counter the added weight in front of them, lose their postural control and end up stressing the lumbar spine.

It’s always a good idea to limit compressive forces on the back. Research shows that having weights alongside the body, rather than held out front of the body at shoulder height, is much more spine-friendly.

If you think about daily activities, such as lifting a big UPS package, or carrying something in front of you, most people would lift or stand in a staggered stance, as it is more stable.  As training is meant to improve function, it makes sense to train in positions that mimic real life, not just a single muscle.

As we age, it becomes even more important to train not just muscle, but movement. Countering muscle disuse through resistance training is a powerful intervention to combat the loss of muscle strength and muscle mass. Independence, mobility, psychological well-being and healthy life expectancy are all benefits.

Lifting groceries or a basket of laundry requires not only strength and mobility, but also good postural control, much like the front-loaded bicep curl. What foot position would give you a larger base of support so you don’t fall? What foot position would give you better stability and balance when doing tasks such as lifting?

Getting back to the bicep curl, the question of which stance was better—parallel or staggered—was recently addressed by two studies at the National Strength and Conditioning Association national conference. The studies showed that the staggered stance provides a bigger base of support anteriorly. Keep in mind that any front-loaded exercise, like the bicep curl, shifts the body’s center of gravity forward. Standing in a staggered stance helps maintain overall stability and balance. It turns out that all muscle activation is the same, no matter your foot position. This includes forward-and-back trunk sway, external obliques, lumbar erector spine, front shin and side shin activity. Whatever stance, staggered or parallel, that you are most comfortable with, without back sway, is good lifting technique. Add an image such as your legs as wood posts, or Krazy glue your feet into the ground, and your bicep curls will look and feel great.https://www.mtexpress.com/wood_river_journal/fitness-guru/article_a6726150-bf8f-11e9-b702-0348f49bc0a0.html
