Possible jobs in sports???

i love sports. i’m a sophmore in high school and have made varsity teams in bball, softball, and golf. basicly i love playing sports. if i dont make it in sports i think it would be smart of me to have a back up plan. my back up plan is majoring in sports management. i think it would be awesome to manage other players. i just dont know if there is any money to be made in that field. it is highly competitive from what i here. does anybody have any other suggestions on what i could do with my life. i want to go to a 4 year university on possibley a sports scholarship i have a 3.0-3.3 gp and am wondering what jobs have the best outlook and make money while having some fun doing the things i love…sports. i’ve looked into sports nutrition sounds interesting but not quite what i’m looking for. sports medicine is alright but i dont want to have to touch anybody else and tell them how to stretch and what not. i think sports management is the way to go possibly with an emphasis on marketing.

Tennis Workout/fitness plan help please :)?

I am currently enrolled in a tennis academy which includes play everyday and conditioning. I play at a county level and regularly play and beat county players. I hit strong classic top spin swing style forehand but my backhand is more varied as i hit a two handed, one handed federer style and slice one handed. I have only recently began hitting the top spin one handed and even though i play many other sports and have a decently athletic build i do not have the required strength to hit the ball with the power and amount of spin i want and think i should be capable of.

I have an athletic build with decent muscle and a muscular stomach and have decent arm muscles. I can run 3000 metre in a decent time and am not a sprinter or really a distance runner.

I basically want to get help with a long term fitness plan which will inprove my core fitness, tennis specific and strength. At my disposle i have a 20kg dumbell set, a multi weight machine, and a cross trainer. Also to help with relaxing muscles and possibe i am fortunate to also have a hottub, swimming pool and sauna.

Any help would be well appreciated.
Thanks
