I introduced my self to my fast twitch muscles last night at the Dixie high school track. Did 10 x 220. I Ran almost full speed for 220 then slow jogged 220. I did not have a watch so I could not guess on how fast I was doing them. Ran about 2 mile warm up and two mile cool down. Felt good to do a little speed work. I had trouble getting out of bed this morning only got in 3. Glad I went out. My left foot arch is sore. Will need to ice it down. |
