Anyone looking for a low-impact cardio alternative...look no further than rucking. Strap up some boots, toss some lbs. on your back, and simply walk.

I've begun to incorporate rucking into my training regiment. It is very effective. I have a 40lb. vest & a 20lb sandbag. I walk 3miles - 4miles every 3 days. You don't have to add that much weight; simply adding ~20lbs will increase kcal expenditure by approximately +40%. I add the sandbag to work the farmer carry (grip strength).

Additional benefits include improved cardio/stamina. Science has shown that low-intensity exercise can be just as effective as high-intensity; for relative strength & endurance... there are just trade-offs with each, low-intensity decrease injury probability but takes up a lot of your time... high-intensity increases injury probability but takes up less time.

Like any other exercise, form is king... you need to maintain good posture, and utilize good gait form... otherwise, you're causing going to start more problems.

Gotta cut weight for a show or competition or match; or just general weight loss... I find this activity to be very effective.
