Yesterday I did a workout before I played which included riding a bike for 15 minutes, and doing a few cycles of pushups, lunges, jumping jacks, sit ups, etc. Needless to say, I am very sore today especially since I haven't worked out like that for a while. When I practiced after exercising, at first I felt very tired. I did my usual warm up of arpeggios and long tones, and I found with these I played very loud naturally, but I was tired. After playing for around forty five minutes I really got calmed down and this eventually helped my playing. I was more successful with controlling my breathing. Exercising was very beneficial to my playing, and I'm excited to see how I feel when doing this more often this week.
