Started out in NY at Equinox training rich clients, while modelling for clinique and a few other places, was really into nutritional ketosis and movement stuff before jumping on the gear to further the career, they all wanted bigger, leaner guys in ads and the competition was really high. Through the clients at the gym got some well paid gigs with celebs.
Key to that body are the following
>less than 10% bf ideally incorporating some kind of fasting or carb management for periods of time as its much easier to manage with those types than making them track their calories
>wider delts to proportionally smaller chest, big arms, trim but defined legs, overdeveloped calves (in proportion to the upper legs)
>as much lat development as possible without too much trap development that overshadows the silhoute.
Program I give clients looking for that type of look. All sets are done controlled, no lockout but stopping just before and stopping a few inches from the bottom at pressing movements
Weighted dips or weighted paralette pushups
Weighted pullups or Weighted chinups
Overhead press variation or incline bench variation
curls or lateral raises or calf raises or glute bridges depending on weak spots and lagging areas
Stationary bike or Stairmaster start at 20 minutes build up to 45 minutes
Heavy leg exercises are not ideal for this kind of thing. cutting them out also allows clients to maximize upper body gains but you could do them if you wanted to. Im not a bodybuilder nor do i find big legs aesthetic, aside from developed glutes which I use glute bridges to maintain. Im 6,4 and I feel like long lean but not bulky is the ideal aesthetic for longer legs.
Cycling helps to develop legs and especially calves. Remember women find this physique the sexiest, its not a bodybuilder, its a lean skinny ripped guy plus 10lbs of muscle. Thats it. Its not that hard to get its just developing the right proportion.
