The training protocol that I have mostly used is 3 sets x 10 sec isometric holds at 50% of max effort with 10-30 seconds rest in between.
Let's give specific examples of isometric exercises. For bench press, load bar with 50% of your max, lower it 1-3 inches above chest level, and hold for 10 seconds. Rest 30 seconds and repeat 3 times. For deadlift, simply pull on bar with 50% effort, without moving it at all. For squat put 50% of your max, squat down to lowest position you train, and sit there for 10 seconds. Don't forget to push your feet into ground to activate all squatting muscles. Imagine that you are squatting up, but don't move.
Here's overall protocol again:
- perform 3 sets of 10 sec isometric holds at 50% intensity
- the isometric exercise should train weakest or maximally stretched position of corresponding dynamic drill
- the isometric exercise should be executed 15-17 minutes before hardest set of corresponding dynamic drill
You may find that during isometric holds you start sweating :] That's because they are a great way to warm up whole body. You get a dynamic strength boost + a great warm up.
Preliminary isometric tension has these three advantages:
- it warms up body
- it has an immediate positive effect on your dynamic strength
- it has a long term positive effect on your lifts
You can utilize preliminary iso tension on your max testing days. Here is scenario: you are testing your Bench Press max. Load 50% of your projected max. Perform 3 sets of 10 sec holds in position where bar is 1-3 inches above chest level (rest 10-30 sec between sets). In next 15 minutes, perform 2-5 sets of 1-2 reps gradually increasing weight to around 90%. Example:
- Rest 3 minutes, 2x50%
- Rest 3 minutes, 2x70%
- Rest 3 minutes, 1x80%
- Rest 3 minutes, 1x85%
- Rest 3 minutes, 1x90%, Rest 3 minutes
Psyche up, and go for your projected max. Good luck.
