Sunderland striker Jermain Defoe shadow boxes at -135 degrees (Video)

Jermain Defoe, Sunderland’s greatest hope for survival

If Sunderland are to stay up this season, then they’ll need Jermain Defoe to keep banging the goals in.

The striker’s goals were central to Sunderland’s survival last season, and he’s continued to chip in with crucial goals this term, with David Moyes’ men showing real signs of improvement of late.

And at 34 years old, Defoe remains as committed and professional as ever.

To maintain peak fitness and condition, Defoe spends time in a cryo chamber at -135 degrees.

And does shadow boxing to keep warm.

Now that’s commitment.
