Courtesy of RH, I got a customized box ( 35 x 33 x 29 cm) to perform my box squats.

Some of you may have heard or seen the Valslide and the exercises that can be performed with it. For those who are keen to purchase one but find the prices to be unfriendly on your budget like me, you may consider using furniture sliders instead. They function similarly to the Valslide and only cost a fraction of its price.

I have been using the Supersliders By Waxman and it works fine with me (though I have never use the Valslide before). To make some money to realize my dream of having my own training facility, I am selling the sliders for SGD 6/piece, meaning it will cost you $12 if you want to own a pair (to dummy proof your understanding). 

It will be featured in the store section in time to come. Meanwhile, pop me an email if you are interested. Happy Sliding! Here is a picture of the one that I'm currently using.
