i hope in 2095 we have more targeted ways to do that.

A lot of progress was slowed by 50 years of mind-warfare.

Look up Emsculpt. It's a fascinating/creepy new device that artificially stimulates core muscular contractions, with visibly more exercised and defined muscles after a few sessions with no changes in lifestyle.

  One of the benefits of lifting heavy things repeatedly over time is increased bone density. Do we know if devices like Emsculpt work to improve bone density? I don't know how the cell-signalling cascade works for putting more calcium-mineral matrix in bones so maybe muscle contraction repetition initiates the cascade, or maybe it's insufficient by itself? Full range of movement training also works to shift lymph back toward the left subclavian vein where it joins venous circulation.[1] The lymphatic system is the primary cellular waste product transport system, and an immune organ in it's own right. From what I read about the place this is a significantly understated feature of exercise and plays a key role in the idea that bed rest is massively counter productive in convalescences and post surgery recovery / outcomes. 1 https://en.wikipedia.org/wiki/Subclavian_vein https://en.wikipedia.org/wiki/Subclavian_vein

    The mechanism you'll find described in the literature for increasing bone density is through heavy stress (compression) on bones. Your muscles aren't positioned to compress like that anyway. Only heavy weights can. The stress very lightly damages the bone matrix, which is then repaired to above the previous strength.

      Correct. Boxers encourage this to happen in their knuckles through things like knuckle pushups. Muy Thai fighters will 'roll' their shins with a bar to cause the same light bone damage.

  TENS units have been around for decades. Every once in a while someone tries to turn it into an exercise machine, but this is mostly marketing, not anything new.
  - crooked-v 8y ago
    This thing is more like a modified MRI machine than a TENS device, which part of the fascinating/creepy quality for me. It's something like orders of magnitude more powerful than TENS.

      It's a pulsed electromagnetic device (PEMF) and they have also been around quite ahile. While they've been show to aid bone growth and they probably help recovery in some other, subtle, ways...EMSculpt is classic snakeoil bullshit.

  I use my motor neurons to electrically stimulate muscle contraction and it doesn't cost me anything. I mean come on... the wires are already hooked up right in to your brain...
  - EamonnMR 8y ago
    But it requires discipline, while attaching wires to yourself does not.

      As many people who bought previous muscle stimulation "as seen on tv" devices bought, it certainly does still require discipline to shock your muscles for an hour or so daily ;)

        I'm going to argue that it would be easier to just go and squat out those 5x5s. The size of the squat rack is another issue however.

        Also if your diet is shit and your gut hangs out over the top of your trousers electrically stimulating your abs isn't going to make the slightest bit of difference aesthetically. At least by actually lifting you're also burning calories.

        Electrically stimulating your abs also burns calories. Using your muscles requires energy, no matter whether they're activated artificially or not.

    The device reportedly causes 20.000 contractions in 30 minutes. And apparently, it's not only volume but also intensity that does the trick. Good luck doing this with you brain, professor.

Do we know if intense weight training combined with cardio workout during childhood and adolescence works to build a life time of improved musculoskeletal outcomes? Has anyone done a longitudinal study in this area?
- z3t4 8y ago
  The strength (and cardio) gains you make as a child will stay. But if you stop training they will go away. But when you however start training again you will have faster gains due to prior training. It all depends on how much you train during your life. While you are the strongest around 30 years old, you will keep most of it until 60 years old if you keep on training. While there are definitely advantages to have been training as a child, I don't think it will be significant when you are 40-50, it will more depend on how active you are during your life. And it's really never too late to start training.
