A couple of people have asked me bout my exercise regime when I mentioned it in the past so I'm gonna show you what I do for my own personal workout routine. I must admit that I am no expert and different people's bodies work differently so what may work for me may not always produce the same results for others.
Here's my general routine:
I do this "Sexy Leg Workout" which I found on the Internet. It's great to also use as a warm up and it really works your legs and abs. I started slowly and tried to complete each exercise as much as I could before building up to the stated number of reps. Before this, I used to do the "Hunger Games Workout" but the trainer seems to have removed it from her site, it was more basic stuff but a good introduction to exercising.
Once I'm done with that I move onto my favourite workout, dance! I use the videos by this Japanese dancer, Miume as inspiration. She's a professional dancer and has done quite a few competitions as well as dance videos and performances for Nico Nico Douga. She often dances to Vocaloid songs but she has tutorial videos on K-pop songs too. She has an official Youtube channel but for some reason, most of the videos have been removed lately, but no worries, it seems quite a number of fans have uploaded her old videos on Youtube anyway.
My second favourite dance workout is her dance of Vocaloid's Romeo and Cinderella song. It's faster and more intense then PonPonPon, but a nice song when I start to get bored. Her partner this time is a dancer called Kimagureprince, his movements appear more professional but I kinda prefer Melochim's bouncier style.
The point is not to actually try to memorise the dance steps but to simply move as much as you can through imitation, though with time, you will get better at following their movements. I just find the songs keep things light hearted and fun which removes the chore of having to exercise, plus I've always admired how lean dancers' bodies are.
I also run on the spot on the balls of my feet for about 1000 steps whilst watching an episode of anime. The anime keeps me distracted so I feel the fatigue later and often, I finish the 1000 steps before the episode ends, so I simply continue and I wind up doing at least a few hundred steps more then intended. Just be careful to not hurt your ankle by landing wrongly whilst running on the spot.
To encourage myself to work out more, I find it alot easier when I set goals. However, do not use weight as a goal for you will wind up gaining weight as you build muscle as muscle's denser then fat, so your body will be toned and trimmer but you'll end up weighing bit more then previously. I used to use some slightly tight clothes as my exercise goals to encourage me to tone up to fit into them but my latest goals this year are cosplay-related as they require me to shape up and look really trim or I'll wind up as a laughing stock amongst the character's fans.
