There’s been a debate for a while over whether or not single-sided power coaching has and benefit over double-sided (doing a one-armed chest press vs doing a traditional barbell bench-press, for instance). There are causes to count on it to be higher, comparable to getting your obliques concerned in a one-armed chest press, and the truth that the full load lifted by the 2 sides individually is greater than the full load in a double-sided elevate. That’s as a result of one aspect is often stronger than the opposite, and the double-sided train might be restricted by the weaker aspect. However as mentioned in a latest article in Alex Hutchinson’s Sweat Science column, research have proven combined outcomes till now.
He goes on to evaluate a latest examine that confirmed a pronounced benefit for single-legged vs. double-legged leg presses and endurance efficiency, nonetheless. The protocol was to alternate legs in a single leg press, vs. elevate with each legs concurrently. The alternate legs led to vital extra enchancment in time to exhaustion in a biking endurance take a look at. This is sensible primarily based on the precept of specificity- it helps if the coaching you do matches the precise motion in your chosen sport. Alternate legs whereas pushing clearly is nearer to the precise biking movement that double-leg presses.
I used to be already doing this as a result of I get pleasure from it. I do “on-bike” leg power coaching, like standing as much as pedal in a giant gear up hill, which is near alternating single-leg presses. I additionally love to do single arm presses, that are near a jab in boxing, and the canoe paddling movement which alternates sides. In all these circumstances I benefit from the movement as a result of it simulates an precise sport motion. However that’s simply me. In case you get pleasure from double-side actions higher, by all means do them. I agree with Alex’s concluding remarks that you need to do no matter kind of power coaching feels higher for you.
