Yes, combining strength workouts with non-strength workouts will reduce the effectiveness of the strength workouts. Of course, that should be acceptable if your goal is broader than pure strength. Per Tom Kurz' Science of Sports Training, page 174: Combining strength exercises and endurance exercises in one workout reduces strength gain without ...

There is so much disinformation ("bro-science") in the answers and comments. I will start with answering the question: Yes, a protein shake once a day as meal replacement is completely safe. This shouldn't worry you. Do you need the extra protein? Probably not, unless you actually do resistance training (and for long term health you should) it will do very ...

When walking, it is recommended that you gently place your foot on the ground heel first with your knee just slightly bent. Some people have actually devoted time to observing the form and posture of individuals from cultures where traditional, natural posture and movement are still intact. Individuals from these cultures very rarely experience back or ...

If they're not causing injuries then they're absolutely fine. If all you're doing is walking a few kms (and the distance is much less than what you're running) then they're perfectly fine. If they start wearing so much that they change your walking style or you start getting symptoms of injuries (such as shin pain) then I would chuck them.

It won't directly, but it can indirectly. You have to have a decent calorie surplus to grow muscle - otherwise your body can't build on what you've done in the gym, and you won't grow any muscles. Running alongside your workout can burn the extra calories that you were going to use to build muscle. This is probably what your friends are referring to. ...

Movement is actually an essential part of maintenance and recovery. Many regenerative processes depend upon impact and activity to repair and build themselves. An example of this is synovial joints. From my knee pain article: Great, [synovial] fluid seems to do everything. Maintains your joints, lubricates them and even helps with shock absorption. So ...

Congratulations, you found the secret muscle group, technically known as the "everything". Being slightly more serious, loaded carries are one of the best exercises you can do to improve strength, muscle mass and general athleticism (according to Dan John) You're right in that your core will be worked, but probably a lot more than you'd imagine. If you ...

Nothing is going to prepare you for being on your feet for long periods of time like being on your feet for long periods of time!! I know that might sound like something out of a National Lampoon movie, but it's true. There are many things that can improve your strength, flexibility, endurance, cardiovascular health, etc, but if you are going to be walking, ...

Short answer, yes, they can. Long answer: Joint movement is essential to the joint's health as the synovial fluid bathes the cartilage and nourishes it. Think of the synovial fluid as "oiling the joint". High impact can be detrimental to the joint surfaces because of the pounding and compressive forces on the cartilage. Running over many years, esp. if ...

You're sore Wednesday because you squatted Monday. Soreness from lifting can easily last two or three days, and even get worse on later days. It's called Delayed Onset Muscle Soreness or DOMS. Since waking up this morning, my lower back is very sore. It is as if I did a heavy workout. I don't understand why this happened. This wasn't as sore yesterday. ...

According to Jack Daniels, the difference is the following: interval training aims to increase your VO2MAX by targeting high intensities, which can't be maintained for a longer period. By design it achieves to maximize the overall volume for those very high intensities because you have breaks between each interval. longer (several kilometres) tempo runs ...

Stretch it. Toe touches and forward bends are a great way to stretch the back out. There are also a ton of Yoga poses that can help you stretch your back in various ways (I recommend checking out yoga.about.com, which has a ton of poses that you can filter by anatomy). You can do these before, during, and after the concert to help your back feel better. ...

If you want to win a 5k, walking is a great start, but will probably not get you there on its own. Fast walking will help you build a strong base level of aerobic fitness. Your heart and lungs will develop and improve your capacity for running. After you build this base, your cardiovascular system needs to learn to function efficiently as you approach (or ...

To answer which one burns more calories, that's pretty straightforward math. Steady state cardio burns calories based upon intensity level x amount of calories per minute . In order to get that number you would need to know your heart rate during exercise and either have the hr monitor calculate the calories burnt totals for you or plug it in to a online ...

Yes, it's a process called glycogenesis. Your larger issue is simply about calories. While your body can produce glycogen from spinach (as an example), there's only 105 calories in a pound of spinach. Spinach actually has some protein in it as well, and your body will use gluconeogenesis to convert some of that protein into glucose. So while from a pure ...

Sarge has a point that if they aren't causing injuries, then it might be fine to wear them. But while the forces when walking compared to running are much lower, you typically wear the shoes much longer (10-14 hours/day vs 0.5-1 hour/day). The reason you replace running shoes is often because the midsole (and probably outersole) are permanently damaged. ...

Yes. A negative one. You will destroy your knees and hips if you wear ankle weights all day long. Your body was not made to handle excess weight at your extremities for that length of time.

I think a key indicator is "Does it hurt when I do this?" If you heel strike while running barefoot, it hurts. Heel striking while walking barefoot, however, in most cases or terrain types doesn't hurt, and is much more comfortable than trying to forefoot strike. Especially if you're wearing shoes, it takes some effort to land forefoot first while ...

To keep going for long time periods, you need to stay hydrated and to take in calories, primarily in the form of carbohydrate, and salt, to replace what you have sweated out. You can generally absorb somewhere around 250-350 calories per hour while you are exercising, and if you are working hard, you can sweat a liter an hour, or more if it is hot. I ...

Well, yes this improves your general health. You don't need to work out every day to be a healthy person. The only reason many people work out is because a lot of people have jobs in which they sit in an office all day. To make up for the lack of movement we get throughout the day, we go to a gym to work out, or go running or cycling. A few thousand years a ...

I am not experienced in this, and I don't have a definite answer, but since this has been asked a week ago and there are no answers yet, I will give the information that I found. Looking through PubMed it's surprisingly hard to find information on this. The keywords which yielded the best results were "treadmill backpack". In particular, I found this ...

I recommend reading the information at the National Insititute of Arthritis and Musculoskeletal and Skin Diseases A part of their website that sticks out to me is: Can Back Pain Be Prevented? One of the best things you can do to prevent back pain is to exercise regularly and keep your back muscles strong. Four specific types of exercises are ...

Sounds possible that you have shin splits http://en.m.wikipedia.org/wiki/Shin_splints They will go away with some time off. This is common with individuals who are new to the level of training that are taking on. My recommendation is to rest for 3 days and start again (rest means you don't have to stop training, just don't do what you have been) As ...

Based on your description this sounds like a very common side stitch (see the wiki entry here: http://en.wikipedia.org/wiki/Side_stitch). As explained in the article (which was informative for me even though I have experienced these off and on when exercising for as long as I can remember) there can be a few factors causing this. For me, it generally ...

This is a surprisingly tricky question to answer. What is fairly unambiguous is that, for most people, increasing activity will correlate with better health. As a race, we are becoming more sedentary with longer periods of inactivity due to the large numbers of jobs that involve sitting at a desk combined with recreation such as web browsers and video games ...

It seems that you've already answered above in the question. I'd just like to add at least two thoughts. 1st is that there are several running techniques, such as pose, and evolution running, to mention just two others. I believe that pelvic rotation should play a part in all of them, but perhaps in different ways. 2nd, is that it'd be useful if you ...

Your request is overly simplistic. That’s why you haven’t been able to find any reliable information. It’s difficult to develop the correlation you want because each of us is an individual capable of losing weight at our own individual pace. Having said that, it is still possible to lose the weight. You’ll need to set a realistic goal, and, expend more ...

Walking with less weight is obviously easier, so you are now burning fewer calories for the same distance. It does feel easier and you are not getting out of breath any more, doesn’t it? (Good things! I’d like to point out) Try to increase speed and inclination (e.g. walk over some hills or steps) or change the exercise (e.g. running or cycling where you can ...

The Gait Cycle Gait essentially is a transition between repeated loss of balance and recovery. During movement there is a cyclic transfer between potential and kinetic energy which will minimize the energy cost of walking. Efficient movement involves preserving and transferring the greatest amount of energy (your momentum) to help propel you forward ...
