how to reset program arduino Leonardo?

hello guys, i've a problem on uploading new program after first program uploaded. is there any trick or method to reset leonardo program? i've tried push and hold the reset button until the program status was 'uploading' but the result was just the same. i'm glad to hear any solution. thanks

press upload, when sketch size shows, double tap the reset (and I'm not a guy by the way)

ohh sorry miss.. i've try what you said.. but it still doesn't work.. it said that

"Sketch uses 3624 bytes (12%) of program storage space. Maximum is 28672 bytes.
Global variables use 148 bytes (5%) of dynamic memory, leaving 2412 bytes for local variables. Maximum is 2560 bytes.
Couldn't find a Board on the selected port. Check that you have the correct port selected. If it is correct, try pressing the board's reset button after initiating the upload.
