A very well thought out question. First, the technical term for holding your breath is called the Valsalva maneuver. In the world of weight lifting it has a distinct purpose: to increase the body's ability to protect the spine under heavy load. The Valsalva maneuver does not work alone. There's a pretty fair treatment of the subject on a Rebock Crossfit ...

The term you are looking for is using a 'spotter', and it is true that bench press can be dangerous, but deaths on it are very rare even for people that work out alone. There are several techniques you can use to bench safer alone. This being said, you should know your limits before lifting alone or use safety bars as shown in the picture below. When ...

You are only likely to fall off of a treadmill if you set it too high for your performance limits, or get distracted while exercising. People generally run in a fairly straight line, and if you are able to keep up with the treadmill's pace, then you shouldn't have any problem staying on. The videos you see are people that try to go from standing on the ...

There are a few considerations when running at night: Making yourself visible to others, i.e. motorists, cyclists, etc. Providing vision for yourself Where to look when running You don't want to be staring down at your feet. Like mountain biking or other high speed pursuits, you want to be looking a few feet ahead so that you know what is coming for ...

My advice will be a bit different, but there's some preliminary things to understand first: Determine the nature of your soreness first: Back pump (where there is an uncomfortable tightness in the lower back) is normal and nothing to be concerned about. Sharp pain, or even a dull pain that is different from general tightness is a symptom of bad form which ...

The safety bars should be set a few inches below the lowest the bar could conceivably go during a successful squat. This way, if the squat goes wrong in any way, you just lower yourself to the bottom of your squat. Do this fast if necessary; release tension in the core, if necessary; jump forward (if the bar is on your back) or backward (if the bar is in ...

Caveat: Proportions is an indicator of how your squat form could look. Actually measuring your limb and torso lengths and trying to mathematically deduce "correct" form is rarely beneficial, and can lead to someone trying too hard with a form that simply doesn't work for them. This is partly because no one has a handle on all of the significant factors that ...

I can't answer this from a manufacturer's standpoint, but from a physics standpoint. Just to compare it to something familiar, this is entirely the same as if your car is running along a flat road, and you turn the engine off, you'll still keep rolling. Why? Momentum! First of all, if you disconnect the power while the treadmill is running, there would ...

No, it's not safe to exercise while in the shower. More importantly, the cost-benefit ratio is too high for this to be effective. Let's consider the "supposed" benefits: 1. Burning calories: How much calories can you realistically burn? Your calorie burn is determined by your intensity and the duration. Your intensity will be low because you're careful not ...

here is a piece of an article I read on your question. "The performance-enhancing effects of nicotine included increased "vigilance and cognitive function" and "reduced stress and body weight", the laboratory reported after a year-long study published by the Forensic Science International journal." link to this article is as follows http://www.foxsports.com....

You should definitely pee during any race even a quarter of that length. The duration of a couple rounds in a bush is going to be negligible in the bigger picture anyway. One of the main reasons why you shouldn't be holding it in that long, is that your bladder will retain a lot of the bacteria that it is trying to flush, and it can end up giving you ...

As AlexL suggests, since you are in a power rack, you can simply set the safeties to a couple inches below squat depth. Then if you need to bail, simply lower your squat beyond your usual squatting depth, rest the bar the safeties, and wiggle your way out. Similarly for the bench press. You should be able to set the safeties in such a way that when your ...

Great question! Especially coming before actually having had bail out (that's the terminology) of a squat. I'm guessing you're back squatting. When failing to stand up during a rep you'll at least have some power left to slow the weight down on the way back down. Use this opportunity and don't hesitate. Release your hands, sit up so the moves backwards, ...

First off, and most importantly - A belt should not be a fix for bad form! That said, a sore back is common when deadlifting. You should get a professional - a real professional - not your local gym-head or 5 $ a hour trainer to coach you. Good form is crucial, especially on heavy exercises. The money you invest in learning the basics will come back ...


3

IMO, a belt shouldn't be necessary until you get to a weight about 2 times your bodyweight, if even then. Fix your form, don't try to patch the problem with a belt. If your back is hurting, you're probably leaning forward and rounding your back to compensate for tight hip flexors or limited ankle dorsiflexion. Video or have someone else video you while you ...

If you're contagious or think you might be, why not just attempt the yoga at your house, and skip the class, and skip possible infection of others.... Also, I'm no doctor, but for sore throats, apple cider vinegar + water + honey = quick fix for sure. Just fast, allow your body to focus on rebuilding your immune system. Do some stretches and yoga, relax, ...

As a general rule, when training ALWAYS check your surfaces. The only time you wouldn't is if you're in a life and death situation, but that's not training. Most parkour videos where there is talking mention or show this. Storror would say "check your surfaces" at least once every other video. As you're starting out, make sure you check your ...

I can only give an anecdotal answer: I find that the tightness of the core from the intra-abdominal pressure added by a full breath becomes negligible once one develops a very strong squat. I think that for a strong squatter, the ability to move the same amount of weight likely exists regardless of breathing method. In my experience of trying many ...

A regular training program will eventually encounter head colds, bad sleep, and other curve balls of life. Do your warmups and make sure you have the mental wherewithal to handle your coordination and strength. Worst case scenario, get in there and do ~75% of your weight or something of the sort. Unless you have a real injury I'd just throttle back the ...

Both the (prominent) arch and the shoulder squeeze during benchpress are forms that are most common in powerlifting. For bodybuilding-style or strength endurance training, they are unnecessary or even counterproductive. The arch The reason for making an arch is two-fold: First, it prevents shoulder impingement as the arch ensures that the angle between ...

Speaking from anecdotal evidence, depending on the severity of the symptoms, there's no need to restrict your gym time or routine. Again, that's going to depend on what your tolerance for pain/numbness is. Personally, I would back off a little on the weights until you have a firm diagnosis. The surgery is a safe and quick procedure (~20 minutes) that ...

Exercise bands are perfectly safe and recommended by many! However, make sure you're using the correct type. I'd suggest something like these which are durable with a good length. Make sure you're not using something like a hip circle band as that will be much too small. I've personally only heard of one exercise band breaking at my local gym. It was while ...

As mentioned in the comments, landmines exercises are about as safe as anything. Having said that, there are some precautions worth taking if you're concerned: Make sure your base is secure. If you're using a plate post, make sure it's heavy enough, and doesn't slide. Bumper plates are great, as they stick to the floor to prevent sliding (got that tip ...

I wouldn't be so definitive about it... I ran a few marathons at ~4hrs and I don't remember feeling like I needed to pee during all for them... I wouldn't say and made a point of not doing either - just not sure I needed it all that much. Depends partly how you plan things beforehand I would say... are you already well hydrated to start with, how often do ...

Here is a good article about biomechanical explanation of bench press with references at the end. To make the long story short; Grasp the barbell with an opposing thumb grip (thumbs wraps around the bar) with your hands shoulder-width or slightly wider than shoulder-width apart. An opposing thumb grip provides more security and control of the barbell. Grasp ...

You are putting yourself at a higher risk. There's always the chance for injury to happen whether you slept for 12 hours or none. What most likely will happen is that you'll feel tired sooner and won't be able to lift as much as you usually do.

Falling of the thread mill is not really a big deal unless of course you hit your head, but it could be just another fun video on youtube. The real problems arise if you keep pushing yourself too hard. Please, go see a doctor before doing intense exercises, it's all fun and games until something snaps and you think you are going to die. http://heartdisease....

I would do internal and external rotation exercises with a resistance band. For internal - Fix a band around a fixed point. Start side on to band. With arm closest to band, fix elbow into waist. Take hand/forearm across body and back, keeping elbow at 90 degrees. External rotation - again fix band. With arm furtherest from band. Start with elbow fixed ...
