Weight Machines in Gyms & Their Similarities

[jewfro18]

So I'm looking to film some instructional videos on how to properly use machines that are commonly found throughout most gyms. However, a Precor chest press and a Cybex chest press, for example, aren't EXACTLY alike.

I was at a gym today and the only chest press they had was a dual-axis one.

My question is, are these machines similar enough that I could just film one video and it would more or less apply to other machines that are similar?

Thanks for any help, much appreciated.

I don't know what each of those chest press machines are, and I'm not going to look them up to find out, but the main technique points are going to be the same.

* Set up so that at the bottom of the ROM, hands sit ~ in line with the xyphoid process (the lowest part of the chest/highest part of the abs).
* Chest up (or, if lying down, point your chest back behind you), elbows squeezed down ~30-45 degrees (or at an even more exaggerated angle for close grip presses for triceps), hug the bench/seat with your scapulas.
* Glutes pressed into the bench/seat, shins vertical, push heels into the floor.
* For high rep/pump sets, inhale on the eccentric and exhale on the concentric.
* For high weight/heavy sets, inhale while locked out and perform Valsalva manouvre, exhaling only after the sticking point on the concentric.

Whatever differences there are between machines, the above technique points should generally be adhered to by 90% of people, and they'll also apply to standard DB/BB bench presses as well.
