T25 advice

I'm now onto the beta phase (started week 2 today) and throughout the alpha phase I always followed the modifier until week 5 when I felt able to follow Shaun T although I still occasionally follow the modifier in the beta phase when I get tired. Definitely keep pushing as I was ready to give up after week 1 of alpha but it is totally worth it in the end! Good luck!!
*edit: I'm 19 and 198.4lbs. When I started, I was 201lbs! Also I never did any sort of exercise until I started T25. Now I'm able to do two workouts a day.

Sounds to me like T25 is the perfect program for you. The modifier is there for that reason. You go as hard as you can following Shaun and when you have to modify you do. Then the next time you do the video you go as hard as you can and each time you get better and better until you no longer need the modifier. As far as "sweating up a storm" goes.. well done. Nothing to worry about there. Let the sweat flow!

My advice. Stick with it. Do the Alpha phase until you can do a good part of the videos without modifying. Even if that means doing the Alpha phase two or three times. The entire point of that phase is to get your lower body and core built up. Then Beta starts to incorporate more upper body and weights, resistance, and less breaks. Because the Alpha is so heavy on the lower body make sure you are really stretching out those calves, glutes, quads etc daily.

I started with T25 a couple of years ago and it's the perfect introductory program. Stick with it, follow the schedule, and give it all you have each and every time and you will get better.

I did this program for a few weeks shortly after having my daughter, but decided I need to focus more on strength training as I'd managed to continue cardio and some body resistance training right up until I gave birth. Anyhow, I got back into T25 October 2015 and was alternating that with Jillian Michael's Body Revolution (rotating full weeks of each program). From October to the end of January 2016, I had such great success. It will test your fitness and your ability to press "play" day-after-day but I can guarantee the results are worth it. I started up Insanity: Max 30 right after I finished the T25 and Body Revolution hybrid. Really liked it but this week I'm starting T25 back up. Today was my first day back and I missed it. I liked Max 30 but, for whatever reason, I think my body responds more positively to what T25 delivers. In regards to you maybe needing to try something else, Tonya is there to offer modified moves. This is done for a reason: so all fitness levels can get into this program and grow with it. I never needed to use the modifications but I LOVE that Shaun T has this option. This is a program you can really develop with. Start with the modifier, get through the program...then maybe go for another round, without the modifications. Good luck! I can promise that if you stick with it, you'll love what you get out of it!
