Calculating band resistance

[Bosshogg300]

how do you calculate band resistance when using them for benching ?

Go to Iron Woody and they have a chart.

In addition to the Iron Woody one, here is the normal Jump Stretch/Elite scale,

In other words....F = k*x . More you stretch the bands, the more force you see. The wider the base you set the bands up with, the higher your spring constant becomes and the more force you see. Just remember that bands are elastic and have a limit to how much they can stretch.

Other factors, such as the age and condition of your bands, the temperature of your gym and where you store them, will determine the actual resistance as well.

Use the charts as a guide and don't worry about the exact amount of resistance. For things like reverse band manuevers, you can set a barbell up and figure out how much is deloaded at the top and bottom of the lift, fairly easy. You could also use some broscience to do this with squats and DLs against bands using a 20 kilo or 45 lb bar and a scale.

For an exact measurement I bought a hanging scale from Tractor Supply ($30.00). Hang the bands on the hook and stretch them for the range of motion. This can give you both the values at the top and bottom of the movement.

Ok im going to check that site out..and will look into the scale idea

you are 100% overthinking this. just put them on and then start adding weight. the weight is just a number what really matters is that you are under a bar and moving it. just make sure you log the weight so you know that next time. just dont worry about it and do work.
