I do a lot of power work, like plyometrics.
I thought it would be a good idea to post some of the workouts that she has me do that are readily available on YOUTUBE.
These workouts are great for runners and triathletes. The best part is that they can be done at home and only take 10 - 15 minutes a few times a week.
Keep in mind, you might have to modify the exercises. That's ok. We all do. Be creative in how you modify.
In other words, don't just give up. If you can't do a push up, just hold yourself up in the position. Do your best. The next time, you'll be able to do more.
This one is one of my favorite core workouts.
Coach Jay Johnson has an entire 8 week program of progression.
Here is the first in the progresssion.
He also has a lunge matrix which should be done as a warm up for your run.
If you really want some fun, do these after your run to build power.
Keep in mind, that your goal should be entire body strength. If you aren't doing anything, these are a great way to get started. If you currently are strength training, these would be a good set of exercises to mix in to keep things interesting.
