Eating an orange or supplementing vitamin C tablets could reduce recovery time after hard training. Vitamin C is a powerful antioxidant, and it is also shown to suppress Cortisol, the nasty hormone that halts fat burning (and is generally just bad). Vitamin C also helps with inflammation, reducing Delayed Onset Muscle Soreness (the painful stiffness) felt after hard sessions. So include an orange or tomatoe in your pre workout meal!
