I mean it really depends. I would like to keep it to a max 90min for a day. Ideally <60min weekdays after work.
I usually do 5 work outs a week. Tennis is 2 of these.
If I am fatigued, then I throw in the jogging, mobility etc. and try to avoid having the training hinder the tennis.
So how about this:
Tuesday/Wednesday, your tennis practice will cover your cardio I imagine
Monday, Wednesday/Friday (or Saturday) 1 hour Gym Session with strength and/or conditioning/power/plyometrics for athelticism
15 minutes per day mobility either morning/evening or on the end of your workout
You then have one day rest and another day where you can do an optional wildcard workout
Lower intensity deload week every 4 or 5 weeks and rest week every 3 months or so
For the 3 Gym sessions you want to make some serious progress on your strength and lifts but you also want to do some conditioning and promote your athleticism for your tennis so you've got some options on how you might split these.
- You could dedicate Monday and Tuesday entirely to your lifting and then do dedicated circuit training/cross training on the third day
- You could do a shorter strength workout on all 3 days (say 30-35 minutes) and have a 10 to 15 minute finisher where you do the conditioning and performance stuff.
- For your lifting you can do full body every day, upper/lower split or push/pull/legs depending on what works best with what you choose above above
For the conditioning exercises I'm thinking about your normal kind of Bootcamp type stuff - climbers, burpees, sprints, spidermans, agility work but also power exercises like KB swings, ball slams and plyometrics like jumping lunges, plyo pushups, drop pushups, box jumps and variations of stepping of a box and performing a jump on landing. Exercises with some rotation like KB Woodchops or throwing a wall ball against the wall with a forehand or backhand type motion I think will be good for the tennis.
Let me know what you think. Adjust the above as suits you but I think something along these lines covers the bases you've described in the time you have available. Easy to say of course as you mentioned before!
