You will want to set up a strategy of progression when using your power twister to allow you to continually challenge yourself with greater amounts of resistance as you become stronger. Here are some tips to follow:

1. Buy several different twisters with varying amounts of resistance. I would recommend that you purchase light, medium, and heavy tension twisters. Start with the light tension model and progress from there.

2. Since you cannot progress in small increments as with free weights or machines, you will be required to employ a wider range of exercise volume, before jumping resistance levels. If you are doing standard repetitions, begin with 5 reps and work up to 20 before attempting the next tension level. If you are doing reps with 5-second peak contraction holds at the end of each rep, start with 5 reps and work your way up to 10 before attempting the next tension level. If you are simply doing peak contraction isometric holds for time, begin with a 1-minute hold and work your way up to 5 minutes before attempting the next tension level.

3. Keep in mind that there are other ways to progress as well. Holding the twister with bent arms makes the exercise easier than with straight arms. In addition, if you are unable to complete a full rep, you can do partial reps to build your strength isometrically. Above all, don't give up just because you hit a sticking point, keep at it!
