Synergistics X- Day 2- Last week I really wasn't fond of it. This week I liked it. Of course, there are those ones that I dread (all chin ups and pull ups) but the boat/plow is great! I used 5 lb weights for the entire workout and Flying Warrior at the end? My legs were shaking so bad I couldn't do it at all! Maybe by the end I'll love this workout! Not giving up on chin ups and pull ups! I WILL be able to do ONE by day 90!
