If you want to build endurance and stamina, you should probably just go run or bike for a really, really long time, right? If you’re training for a marathon, triathlon, or century ride, that’s part of it, sure, but there’s more to the equation.

To stay strong longer out on a race course (or just in your regular workout life!) two factors come into play: VO2 max and lactate threshold. Workouts like CrossFitWODs, performed at high intensity (better known as HIIT or High Intensity IntervalTraining) help boost both in a short but tough session. That might explain why your Instagram feed is packed with images of sweaty shirtless people collapsed on the floor next to barbells.

To really kick your endurance up a notch, the following workouts should be performed keeping the following factors in mind:

*Aim for little to no rest between sets or rounds

*Use a weight that is 50-70% of your 1 rep max for a given exercise

WOD 1: Baseline Row

Start here with a baseline row. If you’re new to rowing, go for a 1K row. Record your time and after you’ve worked with an endurance program for a month, come back to the 1K row and see if you’re time has improved. If you’ve already been rowing, try the 5K row. Remember your pace will have to be a bit slower than with the 1K to avoid burning out.

Remember to initiate the pull with your legs, extend using your core, and finally finish the pull using your arms. The recovery phase begins with arms, then core, then bending the legs. Take powerful, strong pulls and a slow measured recovery.
