Jessica Ennis-Hill's post-pregnancy fitness battle as she bids to become just the third new mum to retain an OIympic title

Only two women in history have given birth and retained their titles in the same Olympic cycle. Jessica Ennis-Hill will be the third if she wins heptathlon gold in Rio.

Shirley Strickland, who won 80m hurdles gold in 1952 and 1956, had a boy in 1953. In 2006 Francoise Mbango Etone, who won triple jump gold in Athens 2004 and Beijing 2008 also had a boy, Niels.

But Ennis-Hill’s feat would be unprecedented because of the many challenges presented by seven disciplines.

I have coached Ennis-Hill, now 30, since she was 13, and I believe she is capable of winning in 12 days’ time on what could be Super Saturday 2 for Team GB, with Mo Farah and Greg Rutherford competing on the same day.

If she can, it will be down not only to bucket loads of determination, natural talent and powers of perseverance but also to the team around her.

I have been documenting her build-up to the Olympics on the blogcoachtorio.com and here I show how she has returned to the top after giving birth to Reggie in July 2014. 

And I predict the scores she will need to win and become Britain’s greatest ever track-and-field athlete.

HEIGHT 

Jess is 5ft 4in (1.65m) and at her best high-jumps 1.95m. To jump 30cm above your head height is pretty exceptional for someone who is diminutive.

Most of the great heptathletes have been 5ft 8in or more, so she’s a rarity. Other coaches said she wouldn’t make it because she’s too small.

A lot of people judge the aesthetic rather than, like a stick of rock, cutting it and seeing what’s written through the middle. But her exceptional speed is Godgiven and like all great sportspeople — the likes of David Beckham, Andre Agassi, Rafael Nadal and Steve Redgrave, for example — she has a phenomenal work ethic which sometimes isn’t recognised.

A large chunk of that comes from within, the philosophy of “I’m going to crash my body because I want to”. She is incredibly focused and hard working.

POST PREGNANCY PBs

I always tell Jess to compare her distances, times or scores with what happened after she came back from having Reggie because that is where she is now.

But as adults we all look at what we used to be able to do and it can be frustrating for her. Having said that, a lot of her season’s bests are in a similar ballpark to her lifetime bests.

MUSCLES

The abdominal muscles become stretched and tear during pregnancy for obvious reasons and this is probably less critical if you’re doing middle or long distance straight line jogging events because you’re just moving in one direction.

But if you look at the nature of the heptathlon, there’s twisting, turning, jumping, so it really was a case of waiting for the abdominal muscles to knit back together which can take six months. Jess couldn’t lift things above her head for three months, so couldn’t do javelin.

We did a lot of plank exercises as opposed to sit-ups but her abs are pretty much back to normal now and she’ll do 180-200 ab exercises three times a week.

MIND

A huge part of Jess’ comeback was being in the right state of mind. Priorities change during pregnancy and again after having the baby. Did she genuinely want to come back or did she prefer to concentrate solely on being a mother?

Was she organised enough to balance home and work life?

I looked at it with scepticism until Reggie was born. Jess had three months off, bar some work with her physiotherapist Alison Rose, bonding with Reggie until that bond was strong enough for her to come back to training.

Until that three months was over I still wasn’t sure.

Once the mind is willing you can train the body. The day Jess stepped back into the gym in November I knew she was committed.

THROWING

Both the javelin and shot put require a lot of twisting and turning. What you saw last season, when Jess struggled with her throwing, was someone who hadn’t been able to do as much work on twisting and turning.

After coming back to training, up to January was spent doing lots of aerobic work and that was very positive because women have increased blood volume, and therefore powers of endurance, after pregnancy.

In the next three months she started throwing but just in straight lines, so by the time the season started we hadn’t done a lot of specific training. Before pregnancy Jess used to do javelin twice a week and now we’re down to one session.

LEGS

During pregnancy the body releases a hormone called relaxin and your ligaments and tendons loosen so the baby can come out. That can take a year to come back and that is when we started seeing responses.

But some of that relaxin has stayed so there have been changes to Jess’s body, where she was very stiff and tight in some areas she’s now not as tight as she was.

You want the tendon to be like a hard rubber ball so when you hit the floor it bounces vigorously back. If it’s softer don’t get the return. She’ll probably never be quite as reactive in her tendons as she was in the past but you work with what you’ve got.

In certain things there will be a positive side, she had very stiff ankles before so pulling her ankle back towards the shin was very tough for her. Now she can do that easily.

FEET

In 2008 Jess had three stress fractures in her right foot, which was the one she took off from in the high jump AND long jump. We made a conscious decision in order to lengthen her career to switch to a left foot take-off in the long jump to halve the amount of jumping.

After four years and the success of London I suggested switching back to the right foot.

Jess wasn’t keen on the idea but came round to it and it was incredibly successful.

But in 2013 she had Achilles problems so couldn’t jump and we never saw it in full effect.

The fact she’s jumped a personal best of 6.63m in Ratingen during a heptathlon in June wasn’t a surprise, we’re just starting to see the result of what was put in place four years ago.

WHAT IS NEEDED TO WIN GOLD?

I think 6,600 points or above will get on the podium and 6,800 will probably be what is needed for gold.

There could be up to eight contenders.

It’s an incredibly compressed field and there aren’t any particularly stand-out athletes.

The question is who can put seven events together without a major hiccup.
