When I played for Boston Breakers in my early twenties, I really stepped up my training, which meant running drills until you're sick.
MLS is a league that is growing. What can I say? The league is more physical: the players here can play 90 minutes or more. There is a little bit more quality in Spain, because it's more technical, but it's difficult to say.
When I was growing up, I played a lot of soccer. I always wanted to be a good soccer player.
At least for soccer players, it comes down to a blend of two types of fitness - your base endurance, which comes from longer distance running, and your speed, which comes from sprint-based workouts.
You realise you have to be physically strong when you come to the Premier League because it is a very intensive league.
I realise the Premier League is a very tough league and I know I have to be stronger.
You can do as many sprints as you want but there's nothing like playing in a 90-minute soccer game. There's no better way to gain your fitness, in my opinion, than playing in consistent games.
The intensity of the Premier League is incredible. The levels of fitness you have to reach just to survive in it is absurd.
With soccer, it's such a dynamic sport. It's important that however you play, you should be training like that.
