I'm on day 6 of 30DS. My goal is to finish at least level 1 as I tried it last year and quit after day 7 . Hopefully I'll manage to finish the whole thing this time. Jillian is right, after 5 days you notice improvements in your endurance and strength. I did it barefoot on exercise mat couple of times, so it is doable. Exercises seem to be bit harder as you don't have extra stability provided by the trainers.
the DVD has arrived... I'm not so much in for losing weight as going ROCK HARD in all the right places... being alert & awake without caffeine would be awesome too. don't have weights yet & not sure how heavy to go - would use 3kg or 4kg for gym use but I'm guessing lighter for this...
OK, just done it. HARD but weirdly I enjoyed it! Loved the rush when I finished. It works so well as each little bit is onl a minute or two, so when I thought I'd die, she moved to something else. Found the star jumps hard (and have much worse pelvic floor than I realised felt like i needed a wee) and the butt kicks and jumping rope realy hard to do, well everything really But it's the first time I've ever "enjoyed" exercise that's not swimming or sex!
The last time I did the full 30 days I also did 60 minutes of cardio a day (a 30 minute run in the morning and 30 minutes on the exercise bike in the evening). That along with eating healthy and I lost 17lbs and toned up a lot. I dropped nearly two full dress sizes.
