So work out at home. There's no excuses to why you can't. You have a floor. That's really all you need.
Okay, so first of all, it's easy to do a simple 30 second plank, or 25 sit ups, or 10 push ups. It really doesn't take all that long. And you can even do exercises in intervals. I have a friend who's a really serious runner, and while her ankle was healing she had to do this sit up routine to keep up her core or something. What she did was 20 sit ups, and a minute rest, 20 sit ups, and a minute rest, and so on for five times. The important thing about working out though is that you can't cheat yourself. You've actually got to do 20 proper sit ups, legs on the ground, arms crossed on your chest, going all the way up.
Other than those simple on the whim exercises, there's also YouTube. It literally has everything FOR FREE. So there's no need to go paying $80 for a special Kayla Itsines workout plan or anything.
The first time I tried one of these I did some kind of ballet cardio thing with Jessica Smith. I loved her workouts for a while, each lasting about half an hour and working out pretty much the whole body. What I liked about it was that being ballet it was partially graceful, and it wasn't all that intense, only getting tired at the very end. Check out her channel at Jessica Smith TV
And this was the first video I did by her:
Another one I tried at the beginning was this really intense series of workouts called 'the 30 day shred'. It was basically a bunch of circuits targeting different parts of the body that went for about half an hour altogether. It was pretty intense, but it definitely worked out everything and you feel amazing when you're done. I think the video was from a fitness channel with all sorts of different gym type classes called Be Fit.
And here's the '30 day shred' video I did. Apparently it's level 2, so maybe it would've been better to start on level 1...
And finally, it's time for my favourite. This channel was recommended by my friend, and it's pretty much the only one I use now. Every single workout is both short and extremely difficult. I've given up a lot, but I'm getting better. I can tell my muscles are getting stronger. I've even begun using her beginners calendar now (which is FREE on her website). This channel is none other than Blogilates!!
Here's a video I did yesterday. It was a little easier than her usual.
I'm actually really liking Pilates right now. I think it's the control, and how you can feel the part of the body you're targeting burn. I mean, I'm still acquainting myself with managing that burn, but I'm just imagining the day when I'll find that I like the feeling. I already feel proud every time I feel it, because I know I'm doing it right and I know I'm actually working it.
So maybe you should work out at home. Even work out right now. Try one of these videos, or just get on the floor and do a few sit ups. It's not like you have many excuses when it's all literally at your fingertips. You really can exert your body anywhere.
