But instead of writing the goal down in a diary or telling a few friends, the Victorian mum-of-one made the pledge on national TV.
Daunting would be an understatement.
On recent episode of This Time Next Year, the 36-year-old told host Karl Stefanovic, “I really want to change my body and my life.”
“I’m a mum and I put on a lot of weight post having my son, so I just thought, ‘Now’s a good time to get fit and have a good challenge’.
“As a mum I thought I’d be back to pre-baby weight (by now), so to still be carrying an extra 30 kilos is really hard. I think your time is very scarce and when you do have time it’s not spent on you.”
Later in the program, Alysha showed off the results of her challenge.
To achieve her goal, each week she worked out with weights four times and did two cardio sessions, with her training ramping up before her first comp next week.
“Really, you want to do well,” she said of the bodybuilding event, “But it doesn't matter on the day. I've won just stepping up on the stage.”
FYI, as phenomenal as these results are, new mums should never feel pressure to "bounce back" to their "pre-baby body". Do what feels right for you and your psychical and mental health.
