Looks like I was only doing half press ups #mybad. Great workout this morning and an awesome turn out for a #lesmills #grit workout as ambassador for @jockey
Carter has become the poster boy for Jockey underwear, which organised the event, and stuck to his promotional duties.
"I was wearing the Jockey performance underwear and, working out at such a high intensity, as wet as it it can get, things were feeling good down stairs. You almost want to encourage people to think a little bit about the underwear they put on when they're training. They think about their shoes, their attire to help them train, but they never really think about their underwear.''
Carter said he would spend Christmas period between Auckland, the Marlborough Sounds and his home province Canterbury.
"The achilles is still a bit tight but the beauty is I've still got plenty of time to recover now over summer and let the body heal.''
