Critically ill patients at Portsmouth's Queen Alexandra Hospital are being put on an exercise bike to help speed up their recovery.
In trials, some have cycled up to three miles a day while they are still in intensive care.
The bike can even be used by patients in a coma.
Consultant Dr Kayode Adeniji said early rehabilitation can help shorten the length of time patients spend in intensive care.
