In this podcast excerpt, the host (Speaker A) asks about glycogen and its impact on the body. Speaker B explains that glycogen is the primary fuel for muscle tension and contraction; when glycogen stores are depleted, muscles lack the energy needed for work, so replenishing glycogen is essential for performance. The conversation then shifts to whether low‑intensity, zone‑2 cardio primarily burns fat or also depletes glycogen, highlighting the distinction between exercise intensity zones and their fuel sources.
