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.

Finally an ab app for me!

I like to do a good bit of cardio and yoga, but for some reason I dislike most ab workouts. This app uses different plank positions that works really well in a short amount of time. The guided coach keeps me focused and from misjudging my time in one pose. I love that the difficulty increases gradually, building strength one day at a time without feeling overwhelmed. This is something I can do at home or on the road, at a moment of my choosing, without a whole bunch of fuss. I can’t wait to see how my body changes after the first thirty days. Thank you so much for making this a thing anyone can enjoy. I finally found an ab app that works for me!

Really like this app

I really like how this app works. I get a reminder in the morning to do the plank work out, and the plank work out takes just a few minutes. There’s about 4 to 5 different plank exercises per day, each pose is for a varying number of seconds. I really really like the pace of each individual work out as well as how I’m gradually increasing in difficulty. I look forward to this each morning - helps me start my day off on the right foot.

Good home exercise routine

I’ve used 6pack in 30days by the same app makers and they are no nonsense, easy to follow, 15-30 min daily exercise routines for the person who may not have time for the gym but still wants to prioritize fitness. I like the plank challenge because it is isometric strength training that does not involve a lot of space or equipment (you need a mat). I’m about a week in to the easiest of three 30-day challenges.
