What type of movement would generally increase resistance in water during exercise?

Moving arms forward while jogging increases resistance in water during exercise because it creates more surface area for the water to push against. When arms are extended forward and moved through the water, they displace a significant volume of water, resulting in greater drag and resistance. This increased resistance enhances muscular engagement, making the exercise more challenging and effective for building strength.

In comparison, paddling with hands provides some resistance, but typically not as much as the forward arm movement due to the limited angle and position of the hands compared to a full arm extension. Jogging quickly can increase overall exertion but has a lesser impact on water resistance since the legs move primarily downward through the water. Swimming slowly, while it does create resistance, does so less effectively than actively pushing the arms forward. The forward movement specifically leverages the hydrodynamic properties of water to maximize resistance, making it the optimal choice in this context.
