Unfortunately I went to bed before your response last night and had decided, since I didn't have an answer, that I'd skip the ride. :-( I really miss being out on my bike. But thanks to you, I'm going to start building in some exercise. Maybe do some very short rides here or there. Hopefully it won't stall me, because I'd really like to finish P2 soon.
i haven't read a lot of the threads lately, but try to keep my eyes open for ones having to do with exercise. i don't think short rides will bother you at all, if you're used to riding so much. for me, i generally lose more when i exercise- but i'm also not used to doing much of anything, so even relatively short rides burn a lot more calories than is normal for me.
i've had days on P2 when i'm too weak to walk from room to room, and other days when i have all kinds of energy. i just started riding last spring, and went 8 miles maybe 1-2x/wk- tougher while on P2, but could do it on a "good" day. then i had a good day in the middle of one round and rode 20. went back to doing 8 miles for the rest of the nice weather last year (i'm in michigan), and then this spring while on P2 i had another good day and rode 15.
it might be good to take a few rides and see how you feel. i think the most important thing is to listen closely to the cues your body is giving you while on P2. if you feel good, keep going and don't worry about it. but if you're struggling, don't push yourself like you might do when not on P2. many people have variations in how they feel from day to day and when you're not eating very much i think it's important to not push it when your body is saying "no".
I was riding around 20 miles a couple times a week and 10-15 a couple times before my last round of P2. During P2, I continued riding but only about 8-10 miles twice a week (and ran and swam other days) and did okay with that. If you are used to riding 65, I bet you'll be okay with the shorter distance. You may want extra protein. I had extra on my workout days and still lost well.
I exercised throughout the 40 days with no problem. However, I did cut back on the intensity. I work out with a trainer and do a lot of weight training and integrate the cardio. Even though my body was supposedly releasing about 2,000 calories into my bloodstream while on HCG, how much nutrition does that fat really store? Too strenuous of exercise on too little nutrition can be hard on you cardiovascularly, so I cut back on my cardio big time.
However, even with just the weight training there would be days that I would feel extremely sick and depleted after a workout. I felt the need to sit and rest after every chore, so I knew I'd overdone it. I'd be the last person to tell anyone not to excercise, but do be cautious and listen to your body. Stay active, but don't ever-exert.
I am going to relay what I was told by two doctors. It is okay to keep the same work out routine while on the VLCD. So if you were used to working out an hour per day you can continue to do so. Now if you are starting the diet and are just now wanting to pick up exercising it is recommended you start with 20 min. of walking so that you don't put your body into a starvation mode.
the only thing I would add to this is if you are used to working out for an hour a day you might find yourself unable to. I personally, from experience, recommend that if you do continue to do this adding a little extra protein to the diet will not cause you to stall or gain, but it will aid in the weakness as well as the healing of the muscles that get broken down when we exercise. Of course, everyone should make their OWN decisions on what is right for them.
