Here's a Fun Leg Day and Run Routine

Two things get tired when you run -- your lungs and legs. Working both while focusing on more muscle stamina will help with those longer timed runs or rucks.

Here is a good running/leg stamina/muscle endurance workout for you to mix into your leg day routine when in a running cycle:

Warmup five minutes/stretch legs (bike/jog/elliptical -- your choice)

Run 20 minutes fast; how far do you get?

Then do the squat/run interval pyramid

Run 100 meters fast

• One squat, run 100 meters
• Two squats, run 100 meters
• Three squats, run 100 meters
• Keep going up to 10, then continue back down the pyramid to one. This is a total of 100 squats, mixed with 1,900 meters of running at a faster than jogging pace.

Swim -- warmup 500 meters with no fins. This is a good way to make any future 500-meter or 500-yard swim test "just another warmup."

Swim with fins nonstop for max distance or ruck for 30 minutes. How far do you get?

Then swim for 30 minutes.
