About this app

Why plank workout?
Planks are the most popular and effective fat burning exercise. They can be easily performed and activate all your muscles, including your core, shoulders, glutes, etc. Planks are the best choice for people with weak knees because they put no pressure on knees.

Maximize the belly fat burning: Planks are more effective than crunches at burning belly fat. Planks activate 100% of your abs, while crunches only involve 64% of them.

Strengthen your core: Plank workout fires up all your core muscle groups, enhances your core strength, and helps you get a strong core.

Reduce back pain: Plank workout can strengthen your back muscles, reduce back pain and lower the risk of back and spinal column injuries.

Improve your posture & balance: Plank workout requires your head, back and feet to be in a straight line. Regularly doing this will improve your balance and posture when sitting and standing.

Accelerate your metabolism: Doing planks keeps your metabolism high for the whole day; this dramatically boosts the fat burning process.

Improve your flexibility: Plank workout stretches all your posterior muscle groups, such as your shoulder blades, glutes and hamstrings, thus improving your flexibility and lowering the risk of injury.

Minimal ads. Used it for 2 wks now & I'm loving it. I haven't worked out for more than 10 yrs altho' I do some walking every so often. Was worried that the workouts will just get harder & harder day by day & that will be too fast for a beginner. It didn't! It was easy then it got harder then it eased back just that little, enough for me to not give up then it goes a notch harder the next day. I love the rest day too! Kinda let you cheat without feeling guilty. I pair this with their back & knee.

This app is great. It has track records your workouts so you can see how many days have you skipped or what level of intensity that you've tried. It offers different level of workouts - perfect for beginners like me. The downside is the ads. Say if you pick 30-day workout, the more you're reaching to the 30th day, the more and longer (unskip-able!) ads appear. If you can bear the ads, then this workout app is perfect for you.

Edit: Still a good app. Lots of diverse plank exercises. Keeps you motivated. 1 short ad after a workout or in between if you pause it. Has warmup and cooldown exercises now. The 1 complaint I have is that the warmup ends with an exercise in a standing position, and there isn't even a second to get to the position on the floor for the 1st plank after that. There is an instance of that during the cooldown too. Would be great if you could give us 5 secs to get to the floor in the future updates.
