Hi Tomislav,

Greg Nuckols makes a good case that this theory is unfounded here: https://www.strongerbyscience.com/muscle-fiber-type/.

To recap:

1. Most muscles in your body have a fairly even split of fast-twitch and slow-twitch muscle fibers; very few muscles are (on average) incredibly fast-twitch or slow-twitch dominant.
   
2. There’s not a practical test to know whether a particular muscle is composed primarily of fast-twitch or slow-twitch fibers. The methods you’d typically use in a gym setting (seeing how many reps you’d get with a particular percentage of your 1rm) have virtually no predictive power.
   
3. The idea that you should train muscles differently based on their predominant muscle fiber type comes from the notion that fast-twitch muscle fibers respond best to heavy weights and low reps, and that slow-twitch muscle fibers respond best to light weights and high reps. Evidence is still very mixed on this point – it’s not yet clear that particular training styles specifically target fast-twitch or slow-twitch fibers in the first place.
   
4. Even if there was good evidence for fiber type specific hypertrophy, and even if there was a good, practical test to know a muscle’s fiber type breakdown, it still wouldn’t change the general recommendation to keep training that muscle with a variety of rep ranges.

With that said, it may still be possible to find out if a lifter progresses better with high or low reps and to adjust to the lifter’s personal physiology, as Barrett suggested. But I'd be really surprised if that had to do with fibre type.

Hi Tony,

Yes, absolutely. This has been suggested before and gotten a number of votes already; please cast yours here: https://muscle.userecho.com/communities/1/topics/24-smart-watch-integration-samsung-galaxy-gear-apple-watch-etc

Hi Bob. It's real time, and you can edit your sets right then and there on the same page where you save them. Best, Carl.

Hi Bob,

To correct a bad entry, you can tap "..." next to that saved set, and tap "edit". Does that work for you?

Great suggestion Bob! I look forward to implementing it.

Until then, what I do is do all my sets for one side. Tap "Save set" inside the app for each, but don't tap "Finish exercise" yet. Then I repeat what I just did for the other side. Not perfect, but gets the job done.

I look forward to implementing your suggestion.

Best,

Carl

Hi guys,

With the short rest, you should you do all your sets on one side, then the next. It's really the best way.

Best,

Carl

Guys, this feature is on the way!

We're now looking for testers ready to upload their program into their Dr. Muscle account via our new Web app. Email us at support@drmuscleapp.com if you're interested, and we'll give you all the details.

Be warned: it's still early, and we expect some bugs. But if you can spare the patience, we'd love to hear from you.

Thanks!

Carl

Hi guys,

Thanks a lot for that suggestion. I can see it's getting some votes already -- nice! I look forward to implementing it.

For now, for the triceps pushdown, I've double checked. You're correct: I did include it in the home programs, from level 2 an up (wasn't overlooked). So far, this hasn't been a problem (looks like people had the equipment at home, you like you do). But if you'd like to do more pulley exercises, you can swap them in (here's how: http://drmuscleapp.com/news/swap/).

All the best,

Carl

Hi Sebastian,

I've just spent 15 min trying to figure out the German Powerblock. It looks like they made some increments heavier than others. Seems odd.

So, I'm not sure we can fit it Dr. Muscle. The way the app works is:

Min weight (in this case, 2.5 kg)

Increments (in this case, variable, but let's pretend 1 kg)

You'd get 2.5, 3.5, 4.5, etc. as recommendations inside the app. Now, I undertand this might not work. So if that suggestion gets lots of votes, we'll add it inside the app.

For now, I'd recommend you set increments to 1 kg and round up.
