To build muscle endurance, limit your recovery time between sets to 30 to 90 seconds. Less resistance, more repetitions and resting for 30 seconds or less between exercises is optimal for building stamina.

Cutting your recovery time and pushing yourself during a workout are great steps toward having more stamina, but don’t forget that your body still deserves some R&R. “You want to train hard, but if you end up training hard every day, you might find that the intensity you put out gets lower and lower.

“There is a time and a place for keeping a steady pace, but if you really want to increase stamina, then increase the intensity

Doing short intervals at a sprint pace. Burpees, Squatsor even push-ups. You’ll know you’ve increased the intensity when you’re out of breath and feel that good burning sensation in whatever muscles are being worked.

Feeling the burn after an intense (but short) bout of burpees is a sign you’re working your muscles. But hey, don’t forget the other two components that comprise the stamina-building trifecta: frequency and duration. Make sure you’re not only going all-out one day per week.

Another important way to increase your stamina is to use the power of your mind. Our minds are the key to either pushing our bodies or stopping short. If we want to increase stamina, we have to be willing to push the last 30%.
