Apples
Eating an apple is a great way to boost exercise endurance. Apples are a good source of an antioxidant called quercetin. One study showed that quercetin — when taken in supplement form — helped people bike longer. Quercetin aids endurance by making oxygen more available to the lungs. Grapes are another quercetin-rich fruit.
The tart cherry juice trick is good for more than just the after-workout pains. I’ve used it to mute the pain from a damaged nerve chunk (CRPS) and after two weeks it’s down to hurting only when inclement weather blows in. The ginger tip is another good one. For those with delicate stomachs, it can be taken in capsules.
