She showed off her slender figure in a bra top and small bicycle shorts as she raised her arms to flex them.

‘The top of this year I decided to really step it up in the gym!’ said the star in her caption.

‘Build more muscle, get my core in order and get stronger! I know my core will probably never be as strong as it used to be but damn it I’m gonna try!’

The crooner added, ‘I have goals and I’m not stopping until I’m there. What were your goals in January? Are you still sticking to it? #letsdothis #gettinstronger.’ 

In December, the star looked to be in great health as she shared a pinup photo.  

‘Happy Thirst-day. Take your vitamins, drink your coffee, do your squats and make today count✨✨✨ #thirstday,’ said the songbird who is a brand ambassador for South Beach Diet.

Thirst-day is when over-the-top sexy photos which beg to be liked are shared on Thursday.

Decker looked toned in her image as she put her backside and legs on display; she also had a golden tan that hinted the image could be from the summer.

Earlier this year she said she had gained some weight.

‘On my tour I had gained some weight and on my 5’1 frame that can be a lot(All the short girls know what I’m talkin bout),’ she began.

‘I noticed when my jeans weren’t buttoning anymore, and I wanted to get back to myself and start feeling strong and healthy and energized again.’

She continued: ‘So I made a change right before this photo shoot and busted my butt! I did 100 lunges a day, squats, 100 crunches and couple mile walks ( I don’t love running) and stuck to a very strict program and lost 6 lbs in 7 weeks!!’

In 2019 she lost 25lbs while on the South Beach Diet.   

She wed Eric Decker in 2013 and in 2014 they welcomed their first child, Vivianne Rose. In 2015 she had her second Eric II and in 2018 her third, Forrest Bradley.    

This Tuesday post comes after her son had a health crisis.

Decker shared a heartbreaking photo of her son Forrest after the two-year-old was hospitalized for the third time in six weeks.

The worried mom shared a post on Thursday as her youngest child recovered at home and told fans about the scary experience seeing her little boy struggling to breathe.

‘Went to the hospital again last night. 3rd time in 6 weeks. Every time he gets a tiny cold he starts wheezing and his oxygen levels drop and heart rate goes up.’ Decker wrote in the caption of a photo of Forrest wearing an oxygen mask.

The singer continued,’Ultimately I’m being told he has Asthma even though he’s pretty young to diagnose. It’s scary to watch his vitals drop, hear his grunting and see his chest struggling so much to take a breath.

Decker said she decided to take Forrest to the hospital after ‘he threw up for the 3rd time ( I think from coughing so much) ( no fever) I knew it was time to take him in.’

The star is also mom to daughter Vivianne Rose, six and son Eric Thomas II, five, with husband Eric Decker.

Decker said Forrest spent the night in hospital under observation after being given stronger medication.

‘Going to see an allergist to see if maybe something is triggering the attacks. So confusing for a parent to have this issue and just not know what to do or why it’s happening.’
