If we've ever talked about fitness before you've likely heard me say the following: "Right cue, right problem, right person, right place & right time." It's not sexy.
It doesn't fit nicely on a t-shirt.
But, it is one of the truest things I know.
The same cue, given to the same person, at two different times in their fitness journey will elicit drastically different results.
That mantra is why I believe so strongly in simple movements for beginners.
Sled work is a great way to improve Leg strength safely because it requires very little technical ability. Walk backward. Push forward. March.
Even people straight off the couch can do these movements. Try putting these same people under a barbell, and you're doing them more harm than good.
If you're a beginner, and most of us are, work your technique for more complicated lifts/movements safely by using low weight. At the same time, you can gradually pile on some more weight with less technical movements like sled marches.
Take your time.
You need to stay in the game to be in the game.
