I want to tone my body, but I don't like running or walking on the treadmill or outdoors. I enjoy playing in the swimming pool. I play in a 11ft pool where I am constantly moving my body to stay afloat. I also do 2-3 laps. I am learning how to dive. My heart rate goes up and I feel tired at the end. I have a good weight and I eat healthy.
Would doing this help me get toned? Do I need to do weights?
