This medium week is designed to help our bodies adjust to the daily load of a new training year. In general, we try to focus on single session days during the first few weeks of the training year to make sure athletes absorb each workout. Still getting used to rollerskis? We recommend some no pole skate skiing and cross-training L3 intervals this week. We continue our series on training theory with an informative presentation by Dr. Stephen Seiler and Kurt Jepson shares his new research on muscle cramping.
