During the Dive
You should keep your exercise intensity as low as possible during the bottom phase of a dive. Mild exercise — on the order of no more than two to three times resting effort, and with very low joint forces — is appropriate during the upper ascent and stop phases of a dive. However, any exercise, particularly exercise involving high joint forces, should be avoided as long as possible after a dive. If you are unable to avoid postdive exercise, you should keep your dive profiles very conservative to minimize your overall risk.
