Hi!

I decided to start another hst-cycle, because the results with hst have been good. I noticed someone requested an hst application for android phones at this forum. Im a software engineering student so i decided to help my own and others hst-training by making this simple app.

The program itself is pretty simple you input how many exercises you are going to do and the increment %, after that you enter the exercises and 15, 10 and 5 rep maxes. Then you return to the main menu and choose continue cycle. After each workout you press the save button on the bottom so the program remembers where to continue.

I will update the program if you find any bugs or think of any improvement ideas.

The program is at android market :

Hst calculator

If you think of any improvement ideas just let me know :)

Looks really good, is it available for Iphones aswell either on retail or jailbreak (cydia)?

If i could change or add anything it would be:
- Include an option for warmup sets
- modify the calculator to always round the weight down to the nearest 2.5.
- Include a settings button to change the numbers for the RM, as some people may like to use 15/12/10/8, 15/10/5/5 etc etc.

The program is only available for Android phones at the moment, but thank you very much for the good improvement ideas :)
 
It was me who mentioned this idea in the FYI sub-forum. This looks like a pretty good start. Thanks for you time and effort.

I like wobbles suggestions. Another suggestion would be to include a notes section for each day. Then of course you need a way to review the notes you have entered to make them useful.
 
Hi!

Thanks for the ideas bulldog :) I updated the program added the custom reps when creating a new cycle and ability to save training log to sd-card root.
I also added the comment section to the continue cycle menu. so the comments will be saved to the training log as well. The training log on the sd-card is .txt file so if
you write your training log to forum its easy to copy paste it from there. If you find any bugs let me know.

Now i need to train more and leave my computer alone :D
 
This is a very good idea. I set up a spreadsheet that calculates maxes with two sets of each exercise. It also has a few 'rep max approximating' routines that might be useful to you (though I'm sure you could figure it all out on your own, sometimes it easier to not have to re-invent the wheel).

I'd be glad to send this to you. I had planned on developing a PC app to handle this and to auto-handle zig-zag (Excel is not the best tool for this sort of thing), but got interrupted with both training and the app due to a health issue. Thankfully, I have been able to start back.

I will install this on my adroid tablet and take a look.
 
Hi!

Im not sure if it is necessary to implement rep max-calculator, because i think it is better to test your rep-maxes and not calculate them, but if many users want it in the program i can implement it.

Do you use these conversion values to calculate rep maxes?

<table border="1"><tbody><tr><td>1</td> <td>1.00</td> </tr> <tr> <td>2</td> <td>.943</td> </tr> <tr> <td>3</td> <td>.906</td> </tr> <tr> <td>4</td> <td>.881</td> </tr> <tr> <td>5</td> <td>.856</td> </tr> <tr> <td>6</td> <td>.831</td> </tr> <tr> <td>7</td> <td>.807</td> </tr> <tr> <td>8</td> <td>.786</td> </tr> <tr> <td>9</td> <td>.765</td> </tr> <tr> <td>10</td> <td>.744</td></tr></tbody></table>

Hey and all of you who use and like to program please give it a 5 star rating, if you do not like the program let me know what is wrong with it :)
 
True; testing is best, but very time consuming. I use a method that takes strength curve into account (at least to a degree).

Though not perfect, it has been very close with several people over several years. Just thot I'd mention it in case.

I note on my tablet it doesn't cosider orientation. Probably not an issue for most users tho, just us tablet types.
 
Nice notice about the tablet-version, i did not even think about the tablet users. Though it sounds bit awkward that some would bring a tablet to gym :D If you like you can send me the method you use and i will test it. I think i will implement the rep-max calculator and somekind of viewer for the gym-log on the program. Keep the imrovement ideas coming :)

Yer a calculator option would be nice. But just have it as a standalone addon to keep it simple. Rather then some complicated system that auto implements the numbers into the program. I'm not sure of the conversion rates but maybe you could have a look at:
http://www.hypertrophy-specific.com/calculator

and see if you can copy that format over.

Edit: Make it available to iphone users! =P
 
I think i will make a separate button on the main menu for the calculator. Simple calculator where you enter reps and weight and the calculator will tell you your 1 - 20 rep maxes.

Sorry wobbles, but i cant release it on iphone, because developer account to appstore costs 100 euros and i am not the biggest fan of apple anyway :D
 
Seems Apple is shooting themselves in the foot with fees like that.

The 10" tablet I have would be cumbersome in the gym, but the smaller ones (7") would probably work well. I suspect the big tables would be more trouble than useful (I can hear it hitting floor already!!).

I got it mostly to play with app development for Android.
 
Great App! Ive been looking for this for a while.

I agree the weight should round to 5 pound increments,

Also, you should make a setting for multiple sets, (ie IF you have two sets of bench press and one set of weighted dips)

And a setting for people who have an A/B workout setup.

Thanks for making such a sweet app,
Chris

Is that why they only have $76B in the bank?

Sorry, had to be said. I'm actually a tech fan so I have an Android phone and an iPad to get the best of both worlds. It's funny how much the schools of thinking there are just like they are in the gym - One side always criticizes the other with notions that are defied by results.

Anyway, I've got a spreadsheet I've developed for my HST work. The formulas in this may be useful. Although there are a variety of tables indicating RMs as a percentage of 1RM, I kind of prefer formulas, especially for coding purposes. The formula used here is taken from Jim Wendler's 5/3/1 book and though I haven't used it enough for HST purposes, it was a rock solid formula for my 5/3/1 work. The numbers it produces for 10 and 15 RMs are a bit lower than what I've seen elsewhere, but I'm sure you can tweak the formula as needed

First I calculate 1RM from 5RM - I know 5RM from my last cycle so that's easy. =MROUND((((5RMweight*5)*.0333)+5RMweight),1)

Then, I reverse it for the others.
=MROUND(((1RMweight-(10*(1rmweight*.0285)))),1)
=MROUND(((1RMweight-(15*(1rmweight*.0285)))),1)

From there you I go to week 6, Friday:
=MROUND(((5rmWeight)+(Interval*2))-(Increment*0),plateIncrement)
Wedesday
=MROUND(((5rmWeight)+(Interval*2))-(Increment*1),plateIncrement)
Monday
=MROUND(((5rmWeight)+(Interval*2))-(Increment*2),plateIncrement)
etc... working backwards

From week 4, Friday:
=MROUND(((10rmWeight)+(Interval*1))-(Increment*0),plateIncrement)
etc...

From week 2, Friday
=MROUND(((15rmWeight)+(Interval*0))-(Increment*0),plateIncrement)
etc.

There are a couple of good features to these formulas. For one, I include the plate increment, so I can account for the fact that my cable machines are incremented in 15 pounds, small dumbells in 2.5 pounds, barbels and larger dumbells in 5 pounds. It also lets me set an increment smaller than my plate size, so if I increment per workout at 2.5 pounds but only have 5 pound plate increments, the rounding function will hold me at one weight on 2 workouts .

I hope these are helpful, although you've probably already got a lot of this built in or have a better way of doing it. If anyone wants to build a spreadsheet from them, please do and let me know how you like it. The Android app looks great, although it'd be hard for me to give up the one I've been using for the past 18 months. I'll definitely check it out and play with it though.
