The “Skyscraper” method is a high rep blast which will get your muscles screaming.
This is an ascending ladder set which usually goes from 1 rep, to 15 reps. Use a weight you’d expect to hit 15 good reps with (trust me, don’t go too heavy!). Perform 1 rep then hold the weights at the end of the rep (ready for the next one) for a 1 count. Now get 2 reps, before holding the start position and counting to 2 . We continue climbing the ladder like this (3 reps, 3 count hold, etc) until we hit a 15 rep round.
Here’s a demo of me using this technique in a DB Shoulder Press. As you can see in the video, I used to call this the ‘Marathon’ method, but ‘Skyscraper’ is a better fit, as you’ll see when you do it.
