Depends if you simply want them for show or not. If you want visible 6 abs. You just need to fix your diet and get a shredded. If you want strong abs you need to train them. But not with high volume workout. It'd be ok, for another sport, but in calisthenics you wouldn't have enough time to recover and it would fuck Up your training. So a few set of a high intensity Low volume is better.

@Chan Woo Park thanks bro. I will

If at the start the progress feels slow then there could be some things that need to be watched out: 1. Obviously if you're still young, progress will be slower in some instances for you than maybe a 20 years old because of testosterone level. Don't worry in time, and if you train and eat the right thing your testosterone levels will keep increasing. 2. Sleep: one of the most important things. It is during the night that the body start working and you rest. Right time should be around 7/9 hours a day. And if you lose sleep one or more days try to get it back in the next ones, or in the same week at least. 3. Food: without food there's no getting better, obviously your body, takes what it needs from the food. Not saying you need a perfect diet, especially at the start, but you should try to eat healthy and take about the right things you need. Carbs, super important if you want to be at your best during training; proteins, for the gains after training, they heal your muscles after you broke them in training in poor words. And try to keep track of how many calories, you take daily. Meat is perfect food for protein, I like pasta for carbs, because it has pretty much everything, a lot of carbs, protein, fats, fibers. 4. In general you should neither smoke, nor drink, but especially if you're an athlete, it's even worse that way. And you're just slowing down your progress. 5. Don't over-train: some people think training more means more gains. But it is quite the opposite, quality over quantity. If you train too much you don't have time to recover and end up hitting plateous and higher risk of injury. I want to specify in calisthenics. In most other sports, you can train hours a day every day. But in calisthenics. A strength related sport it needs more rest. 6. A good warm-up, can let you be at your best of that day during the training. 7. Same for a pre-work out, 30/60 minutes before training. 8. Hydration: if you don't hydrate it can fuck Up your progress and cause injuries during training. Remember we are made 75% from water, it is the most important thing. 2 liters a day. 300/500 ml, 45 minutes before training. 9. Try to stay consistent. 10. And for strength related things, between 6/10 (seconds/reps). So if it is less, change of use a band. You need time under tension. But if it is too much then it becomes more for muscles and endurance growth.

What's your schedule?
