What Jenny is doing with the box over Jorgy’s head, we can only guess.
Workout: Hill Sprints
Find the steepest hill you can find (the DCF hill works great, but a nice sand dune would be even better). Mark off 30 meters.
Perform 10 runs up the hill with a 2 minute rest and a walk back down after each sprint.
Post total time to comments.
A better angle on our BBQ! Everybody (including DCF babies) is on camera! Nice horns, gang!
Short bursts of high intensity sprints–known to benefit muscle and improve exercise performance–can improve the function and structure of blood vessels, in particular arteries that deliver blood to our muscles and heart, according to new research from McMaster University. . .
“As we age, the arteries become stiffer and tend to lose their ability to dilate, and these effects contribute to high blood pressure and cardiovascular disease,” says Maureen MacDonald, academic advisor and an associate professor in the Department of Kinesiology. “More detrimental is the effect that blood vessel stiffening has on the heart, which has to circulate blood”.
The research compared individuals who completed interval training using 30-second “all-out” sprints three days a week to a group who completed between 40 and 60 minutes of moderate-intensity cycling five days a week.
It found that six weeks of intense sprint interval exercise training improves the structure and function of arteries as much as traditional and longer endurance exercise with larger time commitment. . .
