## What is Plank?

Thank you for reaching 100k downloads world wide.

Keen on improving your health & fitness?

Plank is designed to focus on the two primary areas that fitness fanatics want to work on the most.
The plank is one of the best exercises because it tightens the deepest core muscles. It’s a static exercise where you use your arms to raise yourself off the floor and hold the whole body straight and rigid, like a plank of wood.

Getting in shape is a difficult journey. Staying in shape is just as hard. With this collection of videos, your road to fitness will be much simpler. Each training exercise shows you how to workout different muscle groups for maximum results in a minimum amount of time. It's easy enough for anyone to do, and it's a great way to stay motivated during your fitness journey!



Features:
* Simple and fast workouts anyone can do.
* No Equipment required! You can do exercises at any time and any where!
* Dozens of high quality instructional videos that show you exactly what to do. Watch and rewatch the workouts as often as you like.
* Countdown seconds sound
* Calendar to track your workout log
* Weight tracker to track your weight
* You can set the workout reminder
* Add option to change the rest duration between workout cycles

### 1/5 — Pagare 2 volte

*2021-04-21, version 1.1.4*

Se ho pagato la versione full anni fa, perché ora devo ripagare un abbonamento per qualcosa che già avevo pagato ????!!!!!
Non ditemi miglioramenti, perché l’app non è cambiata di una virgola !! Se non che adesso le funzioni sono bloccate e devo fare un abbonamento per sbloccarle !!!!

### 2/5 — Potential

*2020-06-05*

I think I might like this ap but I never really had a chance to give it a try. 

I liked the workout. I chose the very beginner level. It alternated between full arm, a rest period, then from the elbows. It counted down to get started so that you had a chance to get ready. It also sounded tones for the last 5 seconds. That part was good. 

What I didn’t like was that it was only a 3 day trial and you had to purchase more (monthly or yearly options were given) to continue. 

I try to check aps before I download them for any costs involved. I must have missed this one. Deleting the ap

### 1/5 — You only get 2 days

*2020-02-22, version 1.1.4*

What a waste

### 1/5 — Not for us fat folks

*2019-05-04, version 1.1.4*

The weight only goes up to 220.0 pounds. Yeah I know I’m overweight but that’s why I wanted to try this app. Now I’m out the money because measurements aren’t accurate. What a shame.

### 2/5 — Not explanatory

*2019-01-27*

This app does not explain very well how to use and did not provide a pre workout overview so I didn’t know what I was doing.  Additionally, the app does disable power down, so seconds into my first workout the screen was getting out the shutting down.  What a terrible first impression I have.

### 1/5 — Not free

*2018-07-29, version 1.1.2*

Please be honest and tell us that this is not a free app before we download it.

### 5/5 — Good good!

*2018-07-24, version 1.1.2*

I needed to lose a few pounds and thanks to Plank I've done it in a very healthy way. I love this app!

### 5/5 — Good app

*2018-07-23*

I added this app to my morning exercise routine and it helps me shape my day the way I want it to go. Days go much better when you start it off by planking.

### 5/5 — Good app

*2018-07-23*

Getting in shape doesn't have to be that hard. Download this app and work your body anywhere you go!

### 4/5 — Funktioniert nicht mehr
