Slow is smooth, smooth is fast. Bet you've never heard THAT before in your life. But, it is one of best ways to explain that pacing is one of the biggest parts of not blowing yourself up within the first few minutes. With 15 minutes straight of getting work done, all we've got to do to ensure consistent movement is to start the workout at maybe 70% energy output. That way within the last 2 minutes we can dial that up to 90% and finish strong. So start conservative, use the row as a good pacer, and then finish strong.
