Most people notice that their muscles are stronger in some positions than others. But apart from noticing it no one really uses it and takes advantage of this phenomenon in their training.
Today I'm going to show you guys how you can use a cable station to emphasise different parts of a biceps range and strength curve. But first if you don't know what a strength curve is, heres an quick intro.
In all exercises we have whats called a strength curve. Which is basically a graph showing what force the muscles can produce at different joint angles. Biceps have a bell shaped strength curve that looks something like this.
So you can see at the ends of the range (elbow fully flexed and elbow fully extended) the biceps are weakest and in the middle at 90 degrees its strongest.
If you want to get the most out of your training and get best results you need to strengthen all areas of the curve including the end ranges. Think about when you do a barbell curl or especially a preacher curl. The top part of the lift is really easy because there's no resistance. So while the middle is getting a good training effect the top is missing out.
You need to use other exercises throughout your training that hit that top end of the range.
Check out the video and I'll show you an easy way to do it, as well as how you can use it in a mechanical drop set to hit the middle of the strength curve and get more reps than you could normally.
This is just one example. You can try this with triceps, lateral raises and a bunch of other exercises as well. When planning your training have a think about you can hit those areas of the strength curve and range that you normally miss out on and you'll kick your results up another level.
