im doing a cardio program in which i do 7 days a week on my stationary bike
i do two days low intensity two times a day for 30 mins then on the next day i do HIIT for 20 mins goin 30 secs hard 30 secs easy, im also trying to only take about 1800-2000 calories a day im 6'5 215 and im trying to go down to about 185-190 is this a good plan.
Thanks in advance
Weight loss is slightly different, but from a cycling performance standpoint I see a couple other things that are wrong.
1. You would be better off not separating your normal days where you're doing low intensity. How low is "low" anyway? If you can bump up the intensity, you're going to see better results, but what I was getting at is the separation. From a performance standpoint, you want to train your body to flush away lactic acid. You're trying to get it to build capillaries and other things that can provide your muscles oxygen and flush away lactic acid. If you separate your workouts, you're not overloading your legs with lactic acid, so you're not going to get the same results as if you had loaded them up then kept going.
2. It sounds like you're doing interval training with sprints. Usually, from a lactate threshold standpoint, you're supposed to have 500 miles of base miles in before this would do much good, and that's on the road, not on a stationary bike, which is harder. I don't know if you're to that point or not, but, once you do that, you can do intervals, but they're a little different. I think that usually it's recommended to do 1 minute sprints with 2 minutes easier, then do it again. However, these sprints are supposed to absolutely break you down, meaning that they are so hard that you should feel like another 5 seconds is going to kill you. So, with this in mind, I really doubt that you could be doing 20 reps of sprints.
3. The above advice is from a cycling performance/racing standpoint only, not weight loss, but regardless... you really don't need to be doing high intensity stuff without a proper warmup. Doing sprints with no warmup period is just asking for trouble. Even on your normal days you should be warming up with a low intensity for 5 minutes then bumping up the intensity, then cooling down at warmup levels for the last 5 minutes. You shouldn't be doing the same intensity the whole way through, any time.
