Lack of fitness is evil, because it can creep up on you, particularly if you have a sedentary job and don't do a lot of physical activity otherwise, so you might not realise how much it's drifted away. The good news is that of all the things in life where there are no shortcuts but almost guaranteed results if you put the effort in, improving your fitness may well be #1 on the list. If you're not at all fit and haven't been doing regular physical activity for a while, you may need to start slow with the cardio and light with any weights. That's OK. There is no shame in training at your current level, whatever that is. The people I have the most respect for at the gym are the ones who obviously aren't fit yet but who show up and make an effort to improve. The main thing at first is to find a level of intensity where you can complete a decent workout, even if initially it seems very low. It will improve as you continue to train. Also, be very wary of these super-short workouts. When you're first starting out, no amount of bro science or trendy 10 second workouts will substitute for putting the time in regularly to build up your fitness and convert your body mass to the kind you want. Even if right now all you can do is go for a 10 minute walk before you're tiring, do that, but try to do it often. Better that than trying to do something you're not ready for, but then having to stop after just a minute or two. You're unlikely to gain much benefit from that, and if what you're trying to do is that demanding compared to your current ability, it could even be dangerous. On that final point, since I haven't seen anyone else say it yet, remember that if you're significantly increasing the exercise you do and you're not very fit to start with, it's probably a good idea to speak with your doctor to make sure what you're planning to do is sensible for you, particularly if you're a bit older and/or have any significant medical issues that might affect what you can do or how you should train. They can also give you some basic advice on related issues like nutrition, hydration and rest if you don't already know the essentials.
