I understand that you're fed up with all the exercises but in my opinion, exercising is the healthiest way to rapidly lose some pounds.
If you're lacking motivation and getting bored of exercising, you might want to try one of the following tips:
1- Change your workout routine every now and then, maybe every month, you might try to change the place where you workout too.
2- Get a gym buddy to workout with you so you can motivate each other.
3- Get yourself enough rest, stop stressing too much.
4- A cheat meal every week is very important too.
If you're totally not into exercising, there are other solutions but as I've previously said, exercising would do the job perfectly.
Other alternative ways are to follow one of the diet plans that are famous nowadays, like a ketogenic diet
for example, or metabolic cooking
which has also shown some great results with people who have tried it.
There are hundreds of other great nutrition plans that you can follow but those are the ones that I personally know. Good luck!
