Adding an auto percentage max rep calculator based on 1RM
I have a suggestion that could potentially help out a Lot of you.
Adding a PR tracker/calculator to the app. If the client hits a 3RM of
squat for 205, then that could be added to the clients personal record
tracker. The calculator part would take the 3RM, and see what percentage
that is of the 1RM, and state the estimated 1RM. so lets say the clients
1RM is calculated as 220, then when the trainer says to do 8 reps to fail
on 8th rep, the client can see that they should be doing around 175lbs.
Another benefit of this would be if the trainer says to do 3 sets of 1 at
92.5% of the max, but the client has only done a 5RM, the calculator can
find the 1RM so that the trainer can help the client see where they need to
be. Hopefully it makes sense but I think it'll really help People push themselves harder then just grabbing
any weight that they can do just to get it done.

Maybe even have a tab across the top of the exercise demonstration showing estimated or logged 1RM, 3RM, 5RM & 10RM

I utilize primarily RPE for top sets in my coaching. And would love to have an e1rm calculator for my athletes to be able to see their daily 1RM to determine the weight for back off volume work. For example
I could schedule a 1@RPE 8. This would indicate for the athlete to perform a single rep with a weight that subjectively fees like an RPE 8. This value would populate a daily e1rm for the movement. For back off work I would do 73% of e1rm for (insert rep range). If anything at least have the 1RM calculations have the option to utilize RPE as a calculation method. RPE calculator .com might be a good integration?

a simple Rep max calculator so you can prescibe a % or a load based on pesonalised % of a rep max ie 5rm - 3 rm etc

This would be very practical for delivering an entirely online service and eliminating guesswork for the client whilst ensuring progression on the given exercise.
For example, if you wanted the online client to perform
3 sets of 10 @ 70 % of their last 1rm, you could program this in the progression spreadsheet as 3 x 10 @ 70% as opposed to now manually having to calculate the weight-based of a 1 rm that will most likely increase throughout the training block. -

Being able to give weights as a percentage of 1RM in programmes. To be able to type in a percentage of 1RM and it to bring up the weight that is would be a huge timesaver for both trainer and client. When designing strength programmes they are usually done by percentages. At the moment i am having to leave notes in the description for what percentage they are using and what weight that equals and am having to navigate to different websites and spreadsheets to figure it out.

Have a 1RM calculator integral to the app. Clients and trainers can put the weight used and the reps done in to the calculator and it will work out their 1RM. Save having to go to different website to figure it out

This would be a huge help

A calculator that determines how many reps at a weight you would need to increase your estimated 1rm - getting stronger.
I use this via a 1rm calculator through Google however being able to use it via the app by simply adding the feature where your previous workout is shadowed would be far better and user friendly for all clients not to mention for the online PT.
Anyone that has used Recomposer or JeFit knows how this works and how beneficial it is.

Currently debating between Trainerize and another platform because of this. If we can get this it would be awesome.

Being able to see your calculated 1RM as soon as you fill out your reps and weight during the workout allows you or your client to make better decisions in terms of how much heavier to go when selecting weight for the next set.
For example, if a client knows their 1RM is 300lbs but on their 3rd set they see that the weight they chose calculated out to an estimated 1RM of 280, then they know they need to increase their intensity to keep up to what their potential is. Furthermore, they can then begin to select weight levels that show an estimated 1RM that is above their historical actual 1RM, which means they are making progress and working at a high enough intensity to make significant gains.

This is HUGE!!! Clients do not push themselves and manually periodising plans takes a millennium. They should be able to see what reps they need to get to have their projected 1 rep max increase, exactly like the recomposer software. This will mean clients training at an adequate intensity (even with isolation exercises, that you wouldn’t do a 1RM for, but it would be helpful to see what that projected Max is live based on their efforts.
Currently as it stands now you have to fully save the workout and then start the workout again to see what each individual set meant for the estimate 1 rep max of that exercise. -

Strength training requires load selections calculated by an individual's 1RM. Each selected load reflects a percentage that is an estimation of intensity derived from the 1RM. This scale used in conjunction with an RPE and/or RIR scale helps refine appropriate training intensities for the client as their strength progresses toward eventual graduation of their limit strength. Unfortunately, as it stands, your programming options do not allow any of the 3 scales to be utilized to guide training intensities. And I do not see a way to upload my spreadsheets to this platform.

This would be AMAZINGGGG!!!! If they can see what rep scheme at what weight would equal what 1 rep max it would even help intensity on isolation exercises. (obviously never do a 1rm on a tricep extension) but you know if your set wasn't a good one if you aren't beating that projected one rep max.
Only the data populates after the workout and you click save, but there needs to be something to boost intensity intra workout and clients need to see what rep schemes and weights will project their 1 rep max to. It's the BEST way to get better and push yourself every session!!

This would be fantastic to have. Train Heroic has this in their app and is a great feature. Even though I work with primarily Gen. Pop., this is still good info to have and to help educate my clients while showing them actual data.

It would be nice when we are writing out the workouts to be able to program the weight based on the percentage of a max effort performed at the beginning of the program. Along with the percentage being automatically calculated for each subscriber for the program. Right now our coaches have to deliver that information in the description page but it would be nice if it was automated

I have to have Teambuildr app for this and it’s $750 a year. I train strength athletes and teambuildr works great with 1rm and calculating new 1rm maxes but has zero of the auto message and programming features I love about trainerize just need to have both in one place!
