Generally when training, at present, warm-up is usually 2-3min of FH to FH slow drives and 2-3min of BH to BH drives, then 2-3mins of FH loop to blocker and swap, then similar for BH.
This is the ONLY 'STATIC' routines we do, then we move on to some 'SET' routines (of which there are many variations) which always involve movement. left to right, close to away and back in etc, maybe for 15 mins.
After the 'SET' routines we then concentrate on 'IRREGULAR' routines and match play situations, serve and receive, 3rd ball attack, game strategy etc etc
So for an hour training session we break it down to around 25% static. 25% set routines with movement, 50% irregular/match play. ( the session was longer then the % of 'static' would reduce, its basically a warm up ready for the main session
If a stroke or issue has raised its head and been identified as needing additional work by the coaches, then the session may be tailored more towards that specific issue.
Depending on the level and ability of the participants, there may be a shift in how much static routines are used compared to irregular. for 'beginners it could be 50% static with 30% set routines and 20% games (for fun).
One of the key things to remember is to be flexible during a training session, be ready to adapt a session, have a contingency plan etc
Obviously this is just an idea of how a training session can be formulated,
Another thing to remember is that 'Improvement' can be fast, or slow, everyone is different.
How do you evaluate your improvement? ask others, match results and averages etc all point to your improvement but don't always go hand in hand. you may have improved and raised your level, but may still lose to the players you are aiming to beat, but get more points against them, win a game or two say 3-2 instead of 3-0. sometimes a general improvement in shot quality, or movement doesn't always appear straight away in match results. be resilient, steadfast and keep going!!! results will come in the end!!
