Of course you should to try a few new exercises.
One sees if it works or what muscles you claimed it.
Of course you can get that look on the internet also. For example, on Youtube.
But I can only the book "Strength training for every day: The 365 best practices" recommended.
In it you will find countless exercises.
Personally, I find the oars with the struts super.
Simply Expander Hook on the ground and in front of him
go so far back with the two handles until they spun properly.
Then just rowing, as on a boat.
I myself have ordered Level 4.
And have to say that I fit this strength perfectly,
where I almost one stage more could use for both.
Can you bring in the holidays.
Need little space and are not difficult.
Am so very happy !! Therefore, 5 stars !!
