Bests & Worsts Reviews from Amazon

This is by far the best daily training you can do for general training in both strength and cardiovascular. I just really like the simplicity of knowing all I have to do is 100 swings and 10 turkish get ups. The program doesn't leave you taxed so if you want to, you can do other sport activities. I currently do Simple & Sinister 5 days a week and participate in cycling with no degradation in my cycling performance. I just reached the Simple standard the other day (100 one-handed kettlebell swings in 5 minutes and 10 turkish get ups in 10 mins with a 32 kg (~70 lb) kettlebell. In two years, I've noticed that I no longer have any back pain, I feel much stronger, and have more mobility than ever before. Quite recently, I had to carry 50 lb suitcases up and down stairs in the Japan subway system because we couldn't find the elevators. I believe because of this training that this allowed me to not only lift the suitcases without trouble but gave me the cardiovascular fitness to continue going without a lot of rest.
