Squat is very good exercise; it does not require any equipment nor much space to do.
You maybe able to start even right there, right now.
This is the application I installed to help myself doing the squat exercises.
It is very simple and easy to use.
Now, I am on my 9th day, and it has been like below.
Day 1 - 50 squats (OK, it's not too bad.)
Day 2 - 55 squats (Alright. It's just 5 more than yesterday. I can do this.)
Day 3 - 60 squats (Hey, my thighs are getting muscle-ache. I can still do 60 of it though.)
Day 4 - Rest (REALLY!? *I deeply appreciated to this application to give me the day off from the bottom of my heart because I did not expecting it.)
Day 5 - 70 squats (I am back in track now. I feel like my muscle got recovered.)
Day 6 - 75 squats (I knew this was coming. Just plus 5 more than yesterday, right?)
Day 7 - 80 squats (Breathing is important. Inhaling to bending down & exhaling to coming back straight posture.)
Day 8 - Rest (YES! So, I get 1 day rest every 4 days?)
Day 9 - 100 squats (WHAT!? It was 80 squats the day before yesterday!!!)
According to some websites, 15 squats can build the same amount of the muscles as doing 500 abs exercise. So, it's not only me who choose doing squats rather than abs, isn't it?
