They have been heavily documenting their family holiday to the States on social media.
But Cruz Beckham, 12, caused a stir among fans with his most recent Instagram post - which documented his weight training session at the gym.
Clip - David - Victoria - Son - Bench
In the clip, David and Victoria's youngest son is seen performing a bench press, with the help of his brother Brooklyn - but followers were quick to claim Cruz was 'too young' to be embarking on such levels of fitness.
In the video Cruz, clad in a grey vest and tracksuit bottoms, is seen practicing a chest press in the gym, with two weights on each side of the bar.
Way - Reps - Cruz - Fun - Efforts
Managing to puff his way through four reps, Cruz playfully poked fun at his efforts by captioning the clip: 'No gains with @chasenfitness @brooklynbeckham @danieldarri55'
However, his followers immediately took to the comments to pen their concern, and explain he was 'too young' to be lifting weights like his older brothers.
Fan - Efforts - Fitness - Cruzbeckham - Weight
A further fan praised his efforts, but urged him to take his fitness slowly, writing: 'Amazing!!! But @cruzbeckham be careful not to lift too much weight at once'
Other followers however were more stern in their opinions - claiming Cruz should not be pushing himself in the gym at all, as his body is 'still growing'.
'Unless - Personal - Trainer - Thing - Body
One wrote: 'Unless you are at least fifteen, with a qualified Personal Trainer, this is not a thing to do, as your body is still growing. In fact I would say it is not healthy and could cause injury.'
While another added: 'He's going to gym with his father and brothers, you don't get a body like this from running around and doing some fun activities in your holidays. That's how a body looks like when you're training with weights and THAT'S not good for a child's body that's still growing.'
